Struct ComponentId 

pub struct ComponentId(/* private fields */);

Stable, fixed-width identity for a component and its durable namespace.

Implementations

impl ComponentId

pub fn derive(publisher_namespace: &str, component_name: &str) -> ComponentId

Derives an identity from exact publisher/namespace and component name text.

pub fn parse_hex(value: &str) -> Result<ComponentId, ComponentIdParseError>

Parses exactly 64 hexadecimal characters into a component identity.

Errors

Returns a typed parse error for the wrong width or a non-hexadecimal byte.

pub const fn as_bytes(&self) -> &[u8; 32]

Returns the fixed-width identity bytes used by storage key regions.
