[][src]Enum rustc_ap_syntax::source_map::ExternalSource

pub enum ExternalSource {
    Present(String),
    AbsentOk,
    AbsentErr,
    Unneeded,
}

The state of the lazy external source loading mechanism of a SourceFile.

Variants

Present(String)

The external source has been loaded already.

AbsentOk

No attempt has been made to load the external source.

AbsentErr

A failed attempt has been made to load the external source.

Unneeded

No external source has to be loaded, since the SourceFile represents a local crate.

Methods

impl ExternalSource[src]

pub fn is_absent(&self) -> bool[src]

pub fn get_source(&self) -> Option<&str>[src]
