pub struct Variant<'scale, 'resolver, R: TypeResolver> { /* private fields */ }
Expand description

A representation of the a variant type.

Implementations§

Source§

impl<'scale, 'resolver, R: TypeResolver> Variant<'scale, 'resolver, R>

Source

pub fn skip_decoding(&mut self) -> Result<(), DecodeError>

Skip over all bytes associated with this variant. After calling this, Self::bytes_from_undecoded() will represent the bytes after this variant.

Source

pub fn bytes_from_start(&self) -> &'scale [u8]

The bytes representing this sequence and anything following it.

Source

pub fn bytes_from_undecoded(&self) -> &'scale [u8]

The bytes that have not yet been decoded in this variant (this never includes the variant index at the front) and anything following it.

Source

pub fn name(&self) -> &'resolver str

The name of the variant.

Source

pub fn index(&self) -> u8

The index of the variant.

Source

pub fn fields(&mut self) -> &mut Composite<'scale, 'resolver, R> ⓘ

Access the variant fields.
