Trait Hasher

pub trait Hasher:
    Default
    + Write
    + Send
    + Sync
    + 'static {
    type Output: Debug + Clone + Eq + AsRef<[u8]> + 'static;

    // Required method
    fn finalize(self) -> Self::Output;

    // Provided methods
    fn update_with_bcs_bytes(
        &mut self,
        value: &impl Serialize,
    ) -> Result<(), ViewError> { ... }
    fn update_with_bytes(&mut self, value: &[u8]) -> Result<(), ViewError> { ... }
}

The requirement for the hasher type in HashableView.

Required Associated Types

type Output: Debug + Clone + Eq + AsRef<[u8]> + 'static

The output type.

Required Methods

fn finalize(self) -> Self::Output

Finishes the hashing process and returns its output.

Provided Methods

fn update_with_bcs_bytes( &mut self, value: &impl Serialize, ) -> Result<(), ViewError>

Serializes a value with BCS and includes it in the hash.

fn update_with_bytes(&mut self, value: &[u8]) -> Result<(), ViewError>

Includes bytes in the hash.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
