# [−] [src] Struct parity_wasm::elements::CountedWriter

    pub struct CountedWriter<'a, W: 'a + Write> { /* fields omitted */ }

Helper struct to write payload which is preceded by it's own length in bytes.

## Methods

### `impl<'a, W: 'a + Write> CountedWriter<'a, W>` [src]

#### `pub fn new(writer: &'a mut W) -> Self` [src]

New counted writer on top of the given serial writer.

#### `pub fn done(self) -> Result<(), Error>` [src]

Finish counted writer routing, which writes accumulated length and actual payload.

## Trait Implementations

### `impl<'a, W: Debug + 'a + Write> Debug for CountedWriter<'a, W>` [src]

#### `fn fmt(&self, f: &mut Formatter) -> Result` [src]

Formats the value using the given formatter. Read more

## 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`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
