Struct ParseSess

pub(crate) struct ParseSess {
    raw_psess: ParseSess,
    ignore_path_set: Lrc<IgnorePathSet>,
    can_reset_errors: Lrc<AtomicBool>,
}

ParseSess holds structs necessary for constructing a parser.

Fields

raw_psess: ParseSess

ignore_path_set: Lrc<IgnorePathSet>

can_reset_errors: Lrc<AtomicBool>

Implementations

impl ParseSess

pub(crate) fn new(config: &Config) -> Result<ParseSess, ErrorKind>

pub(crate) fn default_submod_path( &self, id: Ident, relative: Option<Ident>, dir_path: &Path, ) -> Result<ModulePathSuccess, ModError<'_>>

Determine the submodule path for the given module identifier.

• id - The name of the module
• relative - If Some(symbol), the symbol name is a directory relative to the dir_path. If relative is Some, resolve the submodule at {dir_path}/{symbol}/{id}.rs or {dir_path}/{symbol}/{id}/mod.rs. if None, resolve the module at {dir_path}/{id}.rs.
• dir_path - Module resolution will occur relative to this directory.

pub(crate) fn is_file_parsed(&self, path: &Path) -> bool

pub(crate) fn ignore_file(&self, path: &FileName) -> bool

pub(crate) fn set_silent_emitter(&mut self)

pub(crate) fn span_to_filename(&self, span: Span) -> FileName

pub(crate) fn byte_pos_same_line(&self, a: BytePos, b: BytePos) -> bool

Determines whether two byte positions are in the same source line.

Trait Implementations

impl LineRangeUtils for ParseSess

fn lookup_line_range(&self, span: Span) -> LineRange

Returns the LineRange that corresponds to span in self.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
