Struct streamson_lib::handler::group::Group

pub struct Group { /* fields omitted */ }

A structure which groups handlers and determines a way how handlers are triggered

Implementations

impl Group

pub fn new() -> Self

pub fn add_handler(self, handler: Arc<Mutex<dyn Handler>>) -> Self

Adds a handler to handler group (builder pattern)

Arguments

• handler - handler to add

Returns

• Group handler

pub fn add_handler_mut(&mut self, handler: Arc<Mutex<dyn Handler>>)

Adds a handler to handler group (mut reference)

Arguments

• handler - handler to add

pub fn subhandlers(&self) -> &[Arc<Mutex<dyn Handler>>]

Iterates through handlers

Trait Implementations

impl Add<Group> for Group

type Output = Self

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for Group

fn clone(&self) -> Group

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for Group

fn default() -> Group

Returns the “default value” for a type.

impl Handler for Group

fn start(
    &mut self,
    path: &Path,
    matcher_idx: usize,
    token: Token
) -> Result<Option<Vec<u8>>, Handler>

Is called when a path is matched

fn feed(
    &mut self,
    data: &[u8],
    matcher_idx: usize
) -> Result<Option<Vec<u8>>, Handler>

Is called when handler receives some data

fn end(
    &mut self,
    path: &Path,
    matcher_idx: usize,
    token: Token
) -> Result<Option<Vec<u8>>, Handler>

Is called when the path is no longer matched

fn is_converter(&self) -> bool

Should be handler used to convert data

fn as_any(&self) -> &dyn Any

Function to allow downcasting
