Trait FileProvider 

Source 
pub trait FileProvider:
    Send
    + Sync
    + 'static {
    // Required method
    fn read_text(
        &self,
        uri: &Uri,
    ) -> impl Future<Output = Result<Option<String>, WorkspaceError>> + TaskSend;
}
Expand description

Supplies text for resources that are not open in the editor.

A successful Some result becomes a version-less Document snapshot; Ok(None) means the provider has no resource for the URI and becomes WorkspaceError::NotFound. Providers report failures — an unsupported scheme, unreadable bytes, or an I/O error — through WorkspaceError, and never cache: every lookup asks the provider again.

The returned future is Send on native targets and may remain local on Worker-hosted WASM, matching the framework’s runtime task boundary.

Required Methods§

Source

fn read_text( &self, uri: &Uri, ) -> impl Future<Output = Result<Option<String>, WorkspaceError>> + TaskSend

Read UTF-8 text for uri, returning None when the resource does not exist and WorkspaceError for other failures.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
