Trait swh_graph::mph::SwhidMphf

pub trait SwhidMphf {
    // Required methods
    fn load(basepath: impl AsRef<Path>) -> Result<Self>
       where Self: Sized;
    fn hash_str(&self, swhid: impl AsRef<str>) -> Option<NodeId>;
    fn hash_str_array(&self, swhid: &[u8; 50]) -> Option<NodeId>;

    // Provided methods
    fn hash_array(&self, swhid: &[u8; 22]) -> Option<NodeId> { ... }
    fn hash_swhid(&self, swhid: &SWHID) -> Option<NodeId> { ... }
}

Minimal-perfect hash function over SWHID.

See DynMphf which wraps all implementor structs in an enum to dynamically choose which MPH algorithm to use with less overhead than dyn SwhidMphf.

Required Methods

fn load(basepath: impl AsRef<Path>) -> Result<Self>where Self: Sized,

fn hash_str(&self, swhid: impl AsRef<str>) -> Option<NodeId>

Hashes a SWHID’s textual representation

fn hash_str_array(&self, swhid: &[u8; 50]) -> Option<NodeId>

Hashes a SWHID’s textual representation

Provided Methods

fn hash_array(&self, swhid: &[u8; 22]) -> Option<NodeId>

Hashes a SWHID’s binary representation

fn hash_swhid(&self, swhid: &SWHID) -> Option<NodeId>

Hashes a SWHID
