Struct StructureMut

pub struct StructureMut<'a> { /* private fields */ }

Allows mutable access to a structure, except for attribute keys which are immutable.

This type wraps the structure in the iterator returned by Body::iter_mut.

Implementations

impl<'a> StructureMut<'a>

pub fn is_attribute(&self) -> bool

Returns true if the structure represents an Attribute.

pub fn is_block(&self) -> bool

Returns true if the structure represents a Block.

pub fn as_attribute(&self) -> Option<&Attribute>

If the Structure is an Attribute, returns a reference to it, otherwise None.

pub fn as_attribute_mut(&mut self) -> Option<AttributeMut<'_>>

If the Structure is an Attribute, returns a mutable reference to it, otherwise None.

pub fn as_block(&self) -> Option<&Block>

If the Structure is a Block, returns a reference to it, otherwise None.

pub fn as_block_mut(&mut self) -> Option<&mut Block>

If the Structure is a Block, returns a mutable reference to it, otherwise None.

Trait Implementations

impl<'a> Decorate for StructureMut<'a>

fn decor(&self) -> &Decor

Returns a reference to the object’s Decor.

fn decor_mut(&mut self) -> &mut Decor

Returns a mutable reference to the object’s Decor.

fn decorate(&mut self, decor: impl Into<Decor>)

Decorate the object with decor in-place.

fn decorated(self, decor: impl Into<Decor>) -> Self

where Self: Sized,

Decorate the object with decor and return the modified value.

impl<'a> Span for StructureMut<'a>

fn span(&self) -> Option<Range<usize>>

Obtains the span information. This only returns Some if the value was emitted by the parser.
