Implementations§

source§

impl FileName

pub fn is_real(&self) -> bool

source

pub fn prefer_remapped_unconditionaly(&self) -> FileNameDisplay<'_>

source

pub fn prefer_local(&self) -> FileNameDisplay<'_>

This may include transient local filesystem information. Must not be embedded in build outputs.

source

source

pub fn macro_expansion_source_code(src: &str) -> FileName

source

pub fn anon_source_code(src: &str) -> FileName
