Implementations

impl FileAppenderBuilder

pub fn encoder(self, encoder: Box<dyn Encode>) -> FileAppenderBuilder

Sets the output encoder for the FileAppender.

pub fn append(self, append: bool) -> FileAppenderBuilder

Determines if the appender will append to or truncate the output file.

Defaults to true.

pub fn build<P: AsRef<Path>>(self, path: P) -> Result<FileAppender>

Consumes the FileAppenderBuilder, producing a FileAppender. The path argument can contain environment variables of the form $ENV{name_here}, where ‘name_here’ will be the name of the environment variable that will be resolved. Note that if the variable fails to resolve, $ENV{name_here} will NOT be replaced in the path.
