Struct PolicyCursor 

pub struct PolicyCursor { /* private fields */ }

Implementations

impl PolicyCursor

pub fn new(data: PolicyData) -> Self

Returns a new PolicyCursor that wraps data in a [Cursor] for parsing.

pub fn new_at(data: PolicyData, offset: PolicyOffset) -> Self

Returns a new PolicyCursor that wraps data in a [Cursor] for parsing at offset.

pub fn parse<P: Clone + Debug + FromBytes + KnownLayout + Immutable + PartialEq + Unaligned>( self, ) -> Option<(P, Self)>

Returns an P as the parsed output of the next bytes in the underlying [Cursor] data.

pub fn parse_slice<PS: Clone + Debug + FromBytes + Immutable + PartialEq + Unaligned>( self, count: usize, ) -> Option<(Vec<PS>, Self)>

Returns a Vec<T> of count items as the parsed output of the next bytes in the underlying [Cursor] data.

pub fn offset(&self) -> PolicyOffset

pub fn len(&self) -> usize

pub fn seek_forward(&mut self, num_bytes: usize) -> Result<(), Error>

Seeks forward by num_bytes, returning a std::io::Error if seeking fails.

pub fn data(&self) -> &PolicyData

Trait Implementations

impl Clone for PolicyCursor

fn clone(&self) -> PolicyCursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyCursor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PolicyCursor

fn eq(&self, other: &PolicyCursor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
