Implementations

impl Value

pub fn into_integer(self, graph: &Graph<'_>) -> Result<u32, ExecutionError>

Coerces this value into an integer, returning an error if it’s some other type of value.

pub fn into_string(self, graph: &Graph<'_>) -> Result<String, ExecutionError>

Coerces this value into a string, returning an error if it’s some other type of value.

pub fn into_syntax_node<'a, 'tree>(
    self,
    graph: &'a Graph<'tree>
) -> Result<&'a Node<'tree>, ExecutionError>

Coerces this value into a syntax node reference, returning an error if it’s some other type of value.
