Struct HeaderExtFlags

Source 
pub struct HeaderExtFlags { /* private fields */ }

Expand description

Fieldset that facilitates compacting the parent type. Used bytes: 1 | Unused bits: 7

Implementations§

Source§

impl HeaderExtFlags

Source

pub const fn new() -> Self

Returns an instance with zero initialized data.

Source§

impl HeaderExtFlags

Source

pub const fn into_bytes(self) -> [u8; 1]

Returns the underlying bits.

§Layout

The returned byte array is layed out in the same way as described here.

Source

pub const fn from_bytes(bytes: [u8; 1]) -> Self

Converts the given bytes directly into the bitfield struct.

Source§

impl HeaderExtFlags

Source

pub fn requests_hash_len(&self) -> <B1 as Specifier>::InOut

Returns the value of requests_hash_len.

Source

pub fn requests_hash_len_or_err( &self, ) -> Result<<B1 as Specifier>::InOut, InvalidBitPattern<<B1 as Specifier>::Bytes>>

Returns the value of requests_hash_len.

#Errors

If the returned value contains an invalid bit pattern for requests_hash_len.

Source

pub fn with_requests_hash_len(self, new_val: <B1 as Specifier>::InOut) -> Self

Returns a copy of the bitfield with the value of requests_hash_len set to the given value.

#Panics

If the given value is out of bounds for requests_hash_len.

Source

pub fn with_requests_hash_len_checked( self, new_val: <B1 as Specifier>::InOut, ) -> Result<Self, OutOfBounds>

Returns a copy of the bitfield with the value of requests_hash_len set to the given value.

#Errors

If the given value is out of bounds for requests_hash_len.

Source

pub fn set_requests_hash_len(&mut self, new_val: <B1 as Specifier>::InOut)

Sets the value of requests_hash_len to the given value.

#Panics

If the given value is out of bounds for requests_hash_len.

Source

pub fn set_requests_hash_len_checked( &mut self, new_val: <B1 as Specifier>::InOut, ) -> Result<(), OutOfBounds>

Sets the value of requests_hash_len to the given value.

#Errors

If the given value is out of bounds for requests_hash_len.

Source§

impl HeaderExtFlags

Source

pub fn from(buf: &[u8]) -> (Self, &[u8])
