Struct SourceBuffer 

pub struct SourceBuffer { /* private fields */ }

A named source buffer: its file name, its NUL-terminated bytes, and a lazily built line index. This is the Rust analog of an llvh::MemoryBuffer registered in a SourceMgr, but it carries its own name.

Implementations

impl SourceBuffer

pub fn from_str(name: impl Into<String>, contents: &str) -> SourceBuffer

pub fn from_slice_check( name: impl Into<String>, contents: &[u8], ) -> SourceBuffer

pub fn name(&self) -> &str

pub fn bytes(&self) -> &[u8]

The source bytes, excluding the trailing NUL terminator.

pub fn raw(&self) -> &[u8]

The raw bytes, including the trailing NUL terminator.

pub fn with_line_index<R>(&self, f: impl FnOnce(&LineIndex, &[u8]) -> R) -> R

Run f with this buffer’s line index, building and caching it on first use.
