Enum stam::OffsetMode

pub enum OffsetMode {
    BeginBegin,
    BeginEnd,
    EndEnd,
    EndBegin,
}

The offset mode represents the ways in which the user can specify an Offset, it expresses whether the cursors (Cursor) for the begin and end positions of the offset are specified as begin-aligned or end-aligned.

Variants

BeginBegin

Offset where both the begin and end positions are specified using a begin-aligned cursor (Cursor::BeginAligned) This is by-far the most common offset mode.

BeginEnd

Offset where the begin position is specified using a begin-aligned cursor (Cursor::BeginAligned) and the end position using an end-aligned cursor (Cursor::EndAligned)

EndEnd

Offset where both the begin and end positions are specified using an end-aligned cursor (Cursor::EndAligned)

EndBegin

Offset where the end position is specified using a begin-aligned cursor (Cursor::BeginAligned) and the begin position using an end-aligned cursor (Cursor::EndAligned)

Trait Implementations

impl Clone for OffsetMode

fn clone(&self) -> OffsetMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for OffsetMode

const IS_DYNAMIC: bool = true

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for OffsetMode

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

Formats the value using the given formatter.

impl<'bytes, Ctx> Decode<'bytes, Ctx> for OffsetMode

fn decode( __d777: &mut Decoder<'bytes>, __ctx777: &mut Ctx ) -> Result<OffsetMode, Error>

Decode a value using the given Decoder.

fn nil() -> Option<Self>

If possible, return a nil value of Self.

impl Default for OffsetMode

fn default() -> Self

Returns the “default value” for a type.

impl<Ctx> Encode<Ctx> for OffsetMode

fn encode<__W777>( &self, __e777: &mut Encoder<__W777>, __ctx777: &mut Ctx ) -> Result<(), Error<__W777::Error>>

where __W777: Write,

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl From<&Offset> for OffsetMode

fn from(offset: &Offset) -> OffsetMode

Converts to this type from the input type.

impl PartialEq for OffsetMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for OffsetMode

impl StructuralPartialEq for OffsetMode
