Struct substrate_parser::propagated::SpecialtySet

pub struct SpecialtySet {
    pub compact_at: Option<u32>,
    pub hint: Hint,
}

Type specialty data (type specialty Hint and compact info) that hierarchically propagates during the decoding.

Compact flag impacts decoding. Hint can determine only the decoded data further processing.

Fields

compact_at: Option<u32>

Compact info.

Some(id) if the parser has encountered type with definition TypeDef::Compact(_) for this SpecialtySet instance.

id corresponds to type id in metadata types Registry.

Once Some(_), never changes back to None.

Must cause parser error if Some(_), but the type inside compact has no HasCompact implementation.

Currently is allowed to be Some(_) for unsigned integers and single-field structs with unsigned integer as a field.

hint: Hint

Hint the parser has encountered for this SpecialtySet instance.

Does not cause parser errors even if resolved type is incompatible.

Could be nullified if no longer relevant, i.e. if passed through some type that is hint-incompatible.

Implementations

impl SpecialtySet

pub fn new() -> Self

Initiate new SpecialtySet.

pub fn reject_compact(&self) -> Result<(), RegistryError>

Check that compact_at field is not Some(_), i.e. there was no compact type encountered.

pub fn update_from_path(&mut self, path: &Path<PortableForm>)

Update Hint from type path, if no hint existed previously.

pub fn forget_hint(&mut self)

Previously found Hint (if there was any) is no longer relevant and is discarded.

pub fn unsigned_integer(&self) -> SpecialtyUnsignedInteger

Apply hint field on unsigned integer decoding.

pub fn hash256(&self) -> SpecialtyH256

Apply hint field on H256 decoding.
