Implementations

impl Hash[−]

pub fn new(hash_slice: &[u8]) -> Hash

pub const fn new_from_array(hash_array: [u8; 32]) -> Hash

pub fn new_unique() -> Hash[−]

unique Hash for tests and benchmarks.

pub fn to_bytes(self) -> [u8; 32]

Trait Implementations

impl AsRef<[u8]> for Hash[+]

[+] Show hidden undocumented items

pub fn as_ref(&self) -> &[u8][−]

Performs the conversion.

impl BorshDeserialize for Hash[+]

[+] Show hidden undocumented items

pub fn deserialize(buf: &mut &[u8]) -> Result<Hash, Error>[−]

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

pub fn try_from_slice(v: &[u8]) -> Result<Self, Error>[−]

Deserialize this instance from a slice of bytes.

pub fn is_u8() -> bool[−]

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl BorshSchema for Hash where
    [u8; 32]: BorshSchema, [+]

[+] Show hidden undocumented items

pub fn declaration() -> String[−]

Get the name of the type without brackets.

pub fn add_definitions_recursively(
    definitions: &mut HashMap<String, Definition, RandomState>
)[−]

Recursively, using DFS, add type definitions required for this type. For primitive types this is an empty map. Type definition explains how to serialize/deserialize a type.

pub fn add_definition(
    declaration: String,
    definition: Definition,
    definitions: &mut HashMap<String, Definition, RandomState>
)[−]

Helper method to add a single type definition to the map.

pub fn schema_container() -> BorshSchemaContainer

impl BorshSerialize for Hash[+]

[+] Show hidden undocumented items

pub fn serialize<W>(&self, writer: &mut W) -> Result<(), Error> where
    W: Write, 

pub fn try_to_vec(&self) -> Result<Vec<u8, Global>, Error>[−]

Serialize this instance into a vector of bytes.

pub fn is_u8() -> bool[−]

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details.

impl Clone for Hash[+]

[+] Show hidden undocumented items

pub fn clone(&self) -> Hash[−]

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)[−]
