# Enum ethcore::ids::TransactionId [−] [src]

    pub enum TransactionId {
        Hash(H256),
        Location(BlockId, usize),
    }

Uniquely identifies transaction.

## Variants

`Hash(H256)`

Transaction's sha3.

`Location(BlockId, usize)`

Block id and transaction index within this block. Querying by block position is always faster.

## Trait Implementations

### `impl Debug for TransactionId`
[src]

#### `fn fmt(&self, __arg_0: &mut Formatter) -> Result`

Formats the value using the given formatter.

### `impl PartialEq for TransactionId`
[src]

#### `fn eq(&self, __arg_0: &TransactionId) -> bool`

This method tests for `self` and `other` values to be equal, and is used by `==`. Read more

#### `fn ne(&self, __arg_0: &TransactionId) -> bool`

This method tests for `!=`.

### `impl Clone for TransactionId`
[src]

#### `fn clone(&self) -> TransactionId`

Returns a copy of the value. Read more

#### `fn clone_from(&mut self, source: &Self)`
1.0.0

Performs copy-assignment from `source`. Read more

### `impl Hash for TransactionId`
[src]

#### `fn hash<__H: Hasher>(&self, __arg_0: &mut __H)`

Feeds this value into the state given, updating the hasher as necessary.

#### `fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher`
1.3.0

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
