Enum RollOff 

#[non_exhaustive]
pub enum RollOff {
    Alpha035,
    Alpha025,
    Alpha020,
    Reserved,
}

Roll-off factor encoded in MATYPE-1 EXT bits [1:0] (DVB-S2/S2X context).

EN 302 307 / EN 302 755 — roll-off is signalled in the MATYPE-1 extension bits when the TS/GS field indicates TS or GFPS. In DVB-T2 the EXT field is reserved.

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.

Alpha035

0b00 — α0.35 (0.35).

Alpha025

0b01 — α0.25 (0.25).

Alpha020

0b10 — α0.20 (0.20).

Reserved

0b11 — reserved / S2X low roll-off.

Implementations

impl RollOff

pub fn from_bits(bits: u8) -> Self

Decode from 2-bit EXT field. Decode from 2-bit EXT field.

pub fn to_bits(self) -> u8

Encode to 2-bit value. Encode to 2-bit value.

pub fn name(self) -> &'static str

Human-readable roll-off label. Human-readable spec display name.

Trait Implementations

impl Clone for RollOff

fn clone(&self) -> RollOff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RollOff

impl Debug for RollOff

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

Formats the value using the given formatter.

impl Eq for RollOff

impl PartialEq for RollOff

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
