Struct InMemoryEmitter

Source

pub struct InMemoryEmitter { /* private fields */ }

Expand description

An in-memory diagnostics emitter.

Diagnostics are pushed to a shared buffer as-is.

§Warning

Do NOT hold a read lock on the buffer across compiler passes as this will prevent the compiler from pushing diagnostics.

Implementations§

Source §

impl InMemoryEmitter

Source

pub fn new() -> (InMemoryEmitter, Arc<RwLock<RawRwLock, Vec<Diag>>>)
