Struct otter_api_tests::flexi_logger::writers::FileLogWriter

pub struct FileLogWriter { /* fields omitted */ }

A configurable LogWriter implementation that writes to a file or a sequence of files.

See writers for usage guidance.

Implementations

impl FileLogWriter

pub fn builder(file_spec: FileSpec) -> FileLogWriterBuilder

Instantiates a builder for FileLogWriter.

pub fn format(
    &self
) -> fn(&mut dyn Write, &mut DeferredNow, &Record<'_>) -> Result<(), Error>

Returns a reference to its configured output format function.

pub fn reset(&self, flwb: &FileLogWriterBuilder) -> Result<(), FlexiLoggerError>

Replaces parts of the configuration of the file log writer.

Note that the write mode and the format function cannot be reset and that the provided FileLogWriterBuilder must have the same values for these as the current FileLogWriter.

Errors

FlexiLoggerError::Reset if no file log writer is configured, or if a reset was tried with a different write mode. FlexiLoggerError::Io if the specified path doesn’t work. FlexiLoggerError::Poison if some mutex is poisoned.
