Enum SetLanguageOutcome 

#[non_exhaustive]
pub enum SetLanguageOutcome {
    Ready,
    Loading(String),
    Unknown,
}

Outcome of SyntaxLayer::set_language_for_path.

Callers that previously tested the return value as a bool should use outcome.is_known() for equivalent behaviour.

Examples

use hjkl_syntax::SetLanguageOutcome;
assert!(SetLanguageOutcome::Ready.is_known());
assert!(SetLanguageOutcome::Loading("rust".to_string()).is_known());
assert!(!SetLanguageOutcome::Unknown.is_known());

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ready

Grammar was already cached (or found fresh on disk) — installed immediately. Buffer will highlight on the next render.

Loading(String)

Grammar is being fetched/compiled on the background pool. Buffer renders as plain text until SyntaxLayer::poll_pending_loads fires the Ready event for this buffer. The inner String is the language name (useful for status-line indicators).

Unknown

Extension unrecognized. No grammar — plain text only.

Implementations

impl SetLanguageOutcome

pub fn is_known(&self) -> bool

true when a grammar was found (either already cached or now in flight). Drop-in replacement for the old bool return value.
