Enum Node 

Source
pub enum Node {
    Tokens(TokensNode),
    Interp(InterpNode),
    At(AtNode),
    Group(GroupNode),
}
Expand description

A single node in a parsed zyn template.

See the ast module for the full node taxonomy.

Variants§

§

Tokens(TokensNode)

Literal Rust tokens passed through unchanged.

§

Interp(InterpNode)

An interpolation expression: {{ expr }} or {{ expr | pipe | ... }}.

§

At(AtNode)

An @-prefixed control-flow or element statement.

§

Group(GroupNode)

A delimited group: (...), [...], or {...}.
