Struct SegmentDescriptor 

pub struct SegmentDescriptor { /* private fields */ }

A single segment descriptor.

Implementations

impl SegmentDescriptor

pub fn offset(&self) -> u32

Data region byte offset within the account.

pub fn count(&self) -> u16

Current element count.

pub fn capacity(&self) -> u16

Maximum element capacity.

pub fn element_size(&self) -> u16

Size of each element in bytes.

pub fn flags(&self) -> u16

Flags.

pub fn is_full(&self) -> bool

Whether the segment is at capacity.

pub fn data_len(&self) -> usize

Total data bytes used by this segment (count * element_size).

pub fn allocated_len(&self) -> usize

Total data bytes allocated (capacity * element_size).

pub fn set_count(&mut self, count: u16)

Set the count.

pub fn set_offset(&mut self, offset: u32)

Set the offset.

pub fn set_capacity(&mut self, capacity: u16)

Set the capacity.

pub fn set_element_size(&mut self, size: u16)

Set the element size.

Trait Implementations

impl Clone for SegmentDescriptor

fn clone(&self) -> SegmentDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl FixedLayout for SegmentDescriptor

const SIZE: usize = SEGMENT_DESC_SIZE

Total byte size on the wire (including any header if applicable).

impl PartialEq for SegmentDescriptor

fn eq(&self, other: &SegmentDescriptor) -> 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.
