Struct Request 

pub struct Request { /* private fields */ }

Available on crate feature recognize_text only.

Shared VNRequest configuration.

Implementations

impl Request

pub const fn recognize_text() -> Self

Build a text-recognition request backed by VNRecognizeTextRequest.

pub const fn kind(&self) -> RequestKind

Return the underlying request kind.

pub const fn with_recognition_level( self, recognition_level: RecognitionLevel, ) -> Self

Select the OCR recognition strategy.

pub const fn with_language_correction(self, enabled: bool) -> Self

Enable or disable language correction.

pub const fn with_prefer_background_processing(self, enabled: bool) -> Self

Mirror VNRequest.preferBackgroundProcessing.

pub const fn with_uses_cpu_only(self, enabled: bool) -> Self

Mirror VNRequest.usesCPUOnly.

pub const fn with_revision(self, revision: usize) -> Self

Override the request revision.

pub const fn recognition_level(&self) -> RecognitionLevel

pub const fn uses_language_correction(&self) -> bool

pub const fn prefer_background_processing(&self) -> bool

pub const fn uses_cpu_only(&self) -> bool

pub const fn revision(&self) -> Option<usize>

Trait Implementations

impl Clone for Request

fn clone(&self) -> Request

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Request

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

Formats the value using the given formatter.

impl Default for Request

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Request

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