Struct davenport::Workspace

pub struct Workspace { /* private fields */ }

A workspace that contains type-erased objects.

The workspace is intended to hold intermediate data used as workspace in computations. It is optimized particularly for the case where the same type is accessed many times in a row.

Usually you do not need to use this type directly. Instead, use define_thread_local_workspace in conjunction with with_thread_local_workspace as described in the crate-level documentation.

Implementations

impl Workspace

pub fn try_insert<W: 'static>(&mut self, w: W) -> Option<&mut W>

Attempts to insert the given object into the workspace.

If the insertion was successful, a reference to the object is returned. Otherwise, None is returned.

pub fn try_get<W: 'static>(&self) -> Option<&W>

pub fn try_get_mut<W: 'static>(&mut self) -> Option<&mut W>

pub fn get_or_insert_with<W, F>(&mut self, create: F) -> &mut Wwhere
    W: 'static,
    F: FnOnce() -> W,

pub fn get_or_default<W>(&mut self) -> &mut Wwhere
    W: 'static + Default,
