Struct CompletionContext 

pub struct CompletionContext {
    pub expecting: Vec<ExpectedTokens>,
    pub replace_from: usize,
}

What the grammar accepts at a cursor position, plus the span the UI should replace when it inserts a completion. Returned by Parser::parse_at_cursor.

Fields

expecting: Vec<ExpectedTokens>

What the grammar accepts at the cursor.

replace_from: usize

The span [replace_from, cursor) the UI should replace — e.g. the F in A1+F. Equals the cursor when there is nothing to replace (right after SUM().

Trait Implementations

impl Clone for CompletionContext

fn clone(&self) -> CompletionContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CompletionContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CompletionContext

fn eq(&self, other: &CompletionContext) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CompletionContext

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
