official actions/checkout README persist-credentials default true
💡 Result:
The default value for the persist-credentials input in the official actions/checkout GitHub Action is true [1][2][3]. This setting controls whether the action configures the authentication token or SSH key with the local git configuration [1][2]. When set to true (the default), the credentials are saved to the local git config, which enables subsequent steps in the same job to execute authenticated git commands [1][4]. The action removes these credentials during post-job cleanup [1][2]. While there has been longstanding community discussion regarding security concerns—specifically relating to implicit token access and the potential for credentials to remain exposed—the default behavior remains true in the official action [5][6][7]. Users who wish to opt out of this behavior can explicitly set persist-credentials to false in their workflow configuration [1][2].

Set GH_REPO for the release step.
The publish job does not check out the repository. gh 2.97.0 does not use GITHUB_REPOSITORY for repository detection. Without GH_REPO, gh release create fails before it verifies the tag, so the package can be published without a GitHub release.

Both mapping factories compile the expression inside the getter delegate. Expression.Compile() then runs on every value read instead of once per mapping, so an export of N items with M mapped members performs N*M compilations.

💡 Result:
These properties belong to the MiniExcel library, a lightweight C# library for Excel and CSV processing [1]. They are used within configuration objects to control how data is read from or written to files. EnableWriteNullValueCell This property is part of the OpenXmlConfiguration class [1][2][3]. It controls whether null or DBNull values in your data should be written as empty cells in the generated Excel (.xlsx) file [1][4]. - Default: True [1][5]. - Usage: Set to false if you want to skip writing null values to the output file [2][5]. StreamReaderFunc / StreamWriterFunc These properties are part of the CsvConfiguration class and are used to handle custom file encodings for CSV files [1][2][6]. - StreamReaderFunc: Allows you to provide a custom function to create a StreamReader, which is useful when you need to specify an encoding other than the default (e.g., GB2312) [1][7]. - StreamWriterFunc: Allows you to provide a custom function to create a StreamWriter for writing CSV files with specific encodings [1][6]. SplitFn This property is part of the CsvConfiguration class [1][4][6]. It allows you to define a custom function (a delegate) to parse or "split" a CSV row [1][4]. This is particularly useful for handling complex CSV formats where the standard delimiter logic might not suffice, such as when using Regex to handle quoted fields or custom separators [1][6]. OpenXmlConfiguration This is a configuration class specifically for OpenXml (Excel.xlsx) operations in MiniExcel [1][8][5]. It contains settings like EnableWriteNullValueCell [2][3] and others (e.g., DynamicColumns, TableStyles) to customize the export process [3]. CsvConfiguration This is a configuration class for CSV operations in MiniExcel [1][6]. It contains settings like StreamReaderFunc, StreamWriterFunc, and SplitFn to customize how CSV data is read or written [1][9][6].

Preserve or reject unsupported MiniExcel v1 settings.
When CsvConfiguration.StreamReaderFunc or CsvConfiguration.SplitFn is configured, ToReadOptions(CsvConfiguration) discards the delegate. The Rust CSV path uses the mapped delimiter and Utf8 default, which can change parsing. When OpenXmlConfiguration.EnableWriteNullValueCell is false, ToWriteOptions(OpenXmlConfiguration) discards the setting. The Rust writer can emit CellValue.Empty as a blank cell instead of skipping null values. Preserve these settings in the Rust contracts, or throw NotSupportedException when they are configured.
