Hints for OCR Engine

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

language_hints: Vec<String>

List of BCP-47 language codes to use for OCR. In most cases, not specifying it yields the best results since it enables automatic language detection. For languages based on the Latin alphabet, setting hints is not needed. In rare cases, when the language of the text in the image is known, setting a hint will help get better results (although it will be a significant hindrance if the hint is wrong).

Implementations

impl Hints

pub fn new() -> Self

pub fn set_language_hints<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of language_hints.

Example

let x = Hints::new().set_language_hints(["a", "b", "c"]);

Trait Implementations

impl Clone for Hints

fn clone(&self) -> Hints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hints

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

Formats the value using the given formatter.

impl Default for Hints

fn default() -> Hints

Returns the “default value” for a type.

impl Message for Hints

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Hints

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