Struct ParallelBuilder 

pub struct ParallelBuilder { /* private fields */ }

Custom configuration for building a Parallel. This struct is not meant to be used directly. Use Parallel::from_vec instead.

Implementations

impl ParallelBuilder

pub fn build(self) -> Parallel

Builds a new Parallel with default or specified configuration.

Example

This is the minimal requirements for using this method:

let mut vector_of_bytes: Vec<Vec<u8>> = Vec::new();
let _build = Parallel::from_vec(vector_of_bytes).build();

pub fn with_quality(self, quality: u8) -> ParallelBuilder

Specifies the quality of compressed images. Defaults to 95 (95% of the original quality).

This method is optional.

pub fn with_device(self, device_num: u8) -> ParallelBuilder

Specifies the number of threads to be used. Defaults to 2.

This method is optional.

Warning

Theoretically, using more threads would mean more workers working on your images. However, spawning many threads has diminishing returns and not to mention it can be costly. Experiment as you please, but if you don’t know what number to put in simply don’t use this method as it is optional.

Trait Implementations

impl Clone for ParallelBuilder

fn clone(&self) -> ParallelBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParallelBuilder

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

Formats the value using the given formatter.

impl Default for ParallelBuilder

fn default() -> ParallelBuilder

Returns the “default value” for a type.

impl Display for ParallelBuilder

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

Formats the value using the given formatter.

impl Hash for ParallelBuilder

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ParallelBuilder

fn cmp(&self, other: &ParallelBuilder) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ParallelBuilder

fn eq(&self, other: &ParallelBuilder) -> 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 PartialOrd for ParallelBuilder

fn partial_cmp(&self, other: &ParallelBuilder) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
