Implementations

impl Value

pub fn is_null(&self) -> bool

Check if this value is null

pub fn into_boolean(self) -> Result<bool, ExecutionError>

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

pub fn as_boolean(&self) -> Result<bool, ExecutionError>

pub fn into_integer(self) -> Result<u32, ExecutionError>

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

pub fn as_integer(&self) -> Result<u32, ExecutionError>

pub fn into_string(self) -> Result<String, ExecutionError>

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

pub fn as_str(&self) -> Result<&str, ExecutionError>

pub fn into_list(self) -> Result<Vec<Value>, ExecutionError>

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

pub fn as_list(&self) -> Result<&Vec<Value>, ExecutionError>

pub fn into_graph_node_ref<'a, 'tree>(
    self
) -> Result<GraphNodeRef, ExecutionError>

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

pub fn as_graph_node_ref<'a, 'tree>(
    &self
) -> Result<GraphNodeRef, ExecutionError>

pub fn into_syntax_node_ref<'a, 'tree>(
    self
) -> Result<SyntaxNodeRef, ExecutionError>

Coerces this value into a syntax node reference, 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>

👎 Deprecated:

Use the pattern graph[value.into_syntax_node_ref(graph)] instead

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

pub fn as_syntax_node_ref<'a, 'tree>(
    &self
) -> Result<SyntaxNodeRef, ExecutionError>
