Enum rslint_parser::Event

pub enum Event {
    Start {
        kind: SyntaxKind,
        start: usize,
        forward_parent: Option<u32>,
    },
    Finish {
        end: usize,
    },
    Token {
        kind: SyntaxKind,

    },
    MultipleTokens {
        amount: u8,
        kind: SyntaxKind,

}

Events emitted by the Parser, these events are later made into a syntax tree with process into TreeSink.

Variants

Start

This event signifies the start of the node. It should be either abandoned (in which case the kind is TOMBSTONE, and the event is ignored), or completed via a Finish event.

All tokens between a Start and a Finish would become the children of the respective node.

Fields of Start

kind: SyntaxKindstart: usizeforward_parent: Option<u32>

Finish

Complete the previous Start event

Fields of Finish

end: usize

Token

Produce a single leaf-element. n_raw_tokens is used to glue complex contextual tokens. For example, lexer tokenizes >> as >, >, and n_raw_tokens = 2 is used to produced a single >>.

Fields of Token

kind: SyntaxKindrange: Range<usize>

MultipleTokens

Fields of MultipleTokens
