Struct ArgumentMetadataItem

Source

pub struct ArgumentMetadataItem<'metadata> {
    pub argument_name: &'metadata [u8],
    pub argument_kind: ArgumentKind,
    pub type_details: Option<IoTypeDetails>,
}

Fields§

§argument_name: &'metadata [u8]

Argument name as bytes.

Expected to be UTF-8, but must be parsed before printed as text, which is somewhat costly.

§argument_kind: ArgumentKind§type_details: Option<IoTypeDetails>

Exceptions:

None for #[env]
None for the last #[output] or return type otherwise in #[init] (see ContractMetadataKind::Init for details)
