Enum Parameter 

#[non_exhaustive]
pub enum Parameter {
    Rate,
    Volume,
    Pitch,
    Range,
    Punctuation,
    Capitals,
    WordGap,
}

Speech parameters, mirroring espeak_PARAMETER from speak_lib.h.

Pass to EspeakNg::set_parameter / EspeakNg::get_parameter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Rate

Speaking rate in words-per-minute (80–450, default 175).

C: espeakRATE

Volume

Output volume (0–200, default 100). 0 = silence.

C: espeakVOLUME

Pitch

Base pitch (0–100, default 50).

C: espeakPITCH

Range

Pitch range / intonation depth (0–100, default 50). 0 = monotone.

C: espeakRANGE

Punctuation

Punctuation announcement mode.

C: espeakPUNCTUATION

Capitals

Capital-letter announcement (0 = none, 1 = sound, 2 = spell, ≥3 = pitch raise in Hz).

C: espeakCAPITALS

WordGap

Pause between words, in units of 10 ms.

C: espeakWORDGAP

Trait Implementations

impl Clone for Parameter

fn clone(&self) -> Parameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Parameter

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

Formats the value using the given formatter.

impl Hash for Parameter

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 PartialEq for Parameter

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