Trait Extract 

pub trait Extract<Output> {
    type LeafFn: ?Sized;

    // Required method
    fn extract(
        node: Option<Node<'_>>,
        source: &[u8],
        last_idx: usize,
        leaf_fn: Option<&Self::LeafFn>,
    ) -> Output;
}

Defines the logic used to convert a node in a Tree Sitter tree to the corresponding Rust type.

Required Associated Types

type LeafFn: ?Sized

Required Methods

fn extract( node: Option<Node<'_>>, source: &[u8], last_idx: usize, leaf_fn: Option<&Self::LeafFn>, ) -> Output

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
