Trait BitStreamVisitor 

pub trait BitStreamVisitor {
    // Required methods
    fn should_enter_block(&mut self, block_id: u32) -> bool;
    fn did_exit_block(&mut self, block_id: u32);
    fn visit(&mut self, block_id: u32, record: Record);

    // Provided method
    fn validate(&self, _signature: Signature) -> bool { ... }
}

A visitor which receives callbacks while reading a bitstream.

Required Methods

fn should_enter_block(&mut self, block_id: u32) -> bool

Called when a new block is encountered. Return true to enter the block and read its contents, or false to skip it.

fn did_exit_block(&mut self, block_id: u32)

Called when a block is exited.

fn visit(&mut self, block_id: u32, record: Record)

Called whenever a record is encountered.

Provided Methods

fn validate(&self, _signature: Signature) -> bool

Validate a bitstream’s signature or “magic number”.
