Struct IdPrefix 

pub struct IdPrefix { /* private fields */ }

A shortened from of an Id.

This is meant for Human interaction.

Implementations

impl IdPrefix

pub const REQUIRED_LENGTH: usize = 2usize

The number of required hex bytes in a prefix (i.e., a prefix must be at least this * 2 hex chars long.)

pub fn from_hex_bytes(input: &[u8]) -> Result<Self, Error>

Construct an new IdPrefix from hex bytes.

Errors

• If the input does not contain (Self::REQUIRED_LENGTH * 2) hex bytes.
• If the input is longer than 64 hex chars.

This is probably not what you want. Use Id::shorten to turn an Id to it’s short form instead.

pub fn resolve<E: Entity + EntityRead>( self, repo: &Repository, ) -> Result<EntityId<E>, Error>

Try to resolve this prefix.

Currently, this lists all ids of the specified Entity and tries to find exactly on with this prefix.

Errors

• If it cannot read all the Entity's IDs.
• If more that one matches.
• If none match.

pub fn is_prefix_of(&self, id: Id) -> bool

Check if this prefix is a prefix of the Id id.
