# Struct pow_sha256::Config [−] [src]

    pub struct Config {
        pub salt: String,
    }

Configuration for generting proof of work Please choose a long, unique value for salt Resistance to dictionary/rainbow attacks depend on uniqueness of the salt

## Fields

`salt: String`

## Implementations

### `impl Config` [src]

#### `pub fn prove_work<T>(&self, t: &T, difficulty: u32) -> Result<PoW<T>> where
T: Serialize,` [src]

Create Proof of Work over item of type T.

Make sure difficulty is not too high. A 64 bit difficulty, for example, takes a long time on a general purpose processor. Returns bincode::Error if serialization fails.

#### `pub fn prove_work_serialized<T>(&self, prefix: &[u8], difficulty: u32) -> PoW<T> where
T: Serialize,` [src]

Create Proof of Work on an already serialized item of type T. The input is assumed to be serialized using network byte order.

Make sure difficulty is not too high. A 64 bit difficulty, for example, takes a long time on a general purpose processor.

#### `pub fn calculate<T>(&self, pow: &PoW<T>, t: &T) -> Result<u128> where
T: Serialize,` [src]

Calculate the PoW score with the provided input T.

#### `pub fn calculate_serialized<T>(&self, pow: &PoW<T>, target: &[u8]) -> u128 where
T: Serialize,` [src]

Calculate the PoW score of an already serialized T and self. The input is assumed to be serialized using network byte order.

#### `pub fn is_valid_proof<T>(&self, pow: &PoW<T>, t: &T) -> bool where
T: Serialize,` [src]

Verifies that the PoW is indeed generated out of the phrase provided.

#### `pub fn is_sufficient_difficulty<T>(
&self,
pow: &PoW<T>,
target_diff: u32
) -> bool where
T: Serialize,` [src]

Checks if the PoW result is of sufficient difficulty
