Enum Method 

#[non_exhaustive]
pub enum Method {
    Floor,
    Ceiling,
}

Available on crate features std or alloc only.

Which direction of threshold crossing counts as a fade.

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.

Floor

Fade detected when mean pixel intensity falls below threshold. Matches the classic “fade to black” case and is the default.

Ceiling

Fade detected when mean pixel intensity rises above threshold (fade to white, or overexposure detection).

Implementations

impl Method

pub const fn is_floor(&self) -> bool

Returns true if this value is of type Floor. Returns false otherwise

pub const fn is_ceiling(&self) -> bool

Returns true if this value is of type Ceiling. Returns false otherwise

impl Method

pub const fn as_str(&self) -> &'static str

Returns a human-friendly name for this method variant.

Trait Implementations

impl Clone for Method

fn clone(&self) -> Method

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Method

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

Formats the value using the given formatter.

impl Default for Method

fn default() -> Method

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Method

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Method

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

Formats the value using the given formatter.

impl Hash for Method

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 Method

fn eq(&self, other: &Method) -> 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 Method

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Method

impl Eq for Method

impl StructuralPartialEq for Method
