Struct Operations 

pub struct Operations { /* private fields */ }

Implementations

impl Operations

pub fn new(operations: Vec<Operation>) -> Operations

pub fn new_orientation(orientation: Orientation) -> Operations

Creates new operations that apply the specified orientation

pub fn prepend(&mut self, operations: Operations)

Prepend operations

let mut ops = Operations::new(vec![Operation::MirrorVertically]);
ops.prepend(Operations::new_orientation(Orientation::Rotation90));

assert_eq!(
    ops.operations(),
    &[
        Operation::Rotate(Rotation::_90),
        Operation::MirrorVertically
    ]
);

pub fn from_read(reader: impl Read) -> Result<Self, Error>

pub fn from_slice(slice: impl AsRef<[u8]>) -> Result<Self, Error>

pub fn to_message_pack(&self) -> Result<Vec<u8>, Error>

pub fn operations(&self) -> &[Operation]

pub fn operation_ids(&self) -> Vec<OperationId>

pub fn unknown_operations(&self) -> &[String]

Returns information about all operations that were unknown when deserializing

pub fn orientation(&self) -> Option<Orientation>

Returns an Orientation if all operations can be reduced to that

assert_eq!(
    Operations::new(vec![
        Operation::Rotate(Rotation::_180),
        Operation::Rotate(Rotation::_270)
    ])
    .orientation(),
    Some(Orientation::Rotation90)
);

assert_eq!(
    Operations::new(vec![
        Operation::Rotate(Rotation::_90),
        Operation::MirrorHorizontally
    ])
    .orientation(),
    Some(Orientation::MirroredRotation270)
);

assert_eq!(
    Operations::new(vec![
        Operation::MirrorHorizontally,
        Operation::MirrorVertically,
        Operation::Rotate(Rotation::_270),
        Operation::MirrorHorizontally,
    ])
    .orientation(),
    Some(Orientation::MirroredRotation270)
);

Trait Implementations

impl Debug for Operations

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Operations

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Operations

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

impl Serialize for Operations

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
