Struct ProjectionGroupPrefix 

pub struct ProjectionGroupPrefix { /* private fields */ }

A transient canonical prefix for one published projection generation.

Implementations

impl ProjectionGroupPrefix

pub fn from_bytes(bytes: Vec<u8>) -> Result<Self, ProjectionKeyError>

Parses a syntactically canonical zero-or-more-component prefix.

Exact leading-component validation still requires the matching checked projection group schema.

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

Borrows the canonical prefix bytes.

pub const fn identity(&self) -> &ProjectionIdentity

Returns the projection identity encoded by the prefix.

pub const fn generation(&self) -> ProjectionGeneration

Returns the generation encoded by the prefix.

pub fn components(&self) -> &[CanonicalValue]

Returns the syntactically validated complete leading components.

pub fn exclusive_successor(&self) -> Vec<u8>

Returns the lexicographic exclusive successor for a prefix range.

A valid prefix always begins with 0x47, so a successor always exists.

Trait Implementations
