Struct Snr 

pub struct Snr(/* private fields */);

Signal-to-noise ratio represented in centibels (0.1 dB units).

This uses a slightly finer unit than whole decibels while still staying compact and integer-friendly. Some common LoRa radios report SNR in quarter-dB steps. Converting those readings into centibels requires rounding, introducing at most 0.5 cB (0.05 dB) of error.

Implementations

impl Snr

pub const fn from_centibels(centibels: i16) -> Snr

Construct an SNR value directly from centibels.

pub const fn from_decibels(db: i8) -> Snr

Construct an SNR value from whole decibels.

pub const fn from_quarter_db_steps(steps: i16) -> Snr

Construct an SNR value from quarter-dB steps, rounding to the nearest centibel.

pub const fn as_centibels(self) -> i16

Return the stored value in centibels.

Trait Implementations

impl Clone for Snr

fn clone(&self) -> Snr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Snr

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

Formats the value using the given formatter.

impl Default for Snr

fn default() -> Snr

Returns the “default value” for a type.

impl Hash for Snr

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

where __H: Hasher,

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 Snr

fn cmp(&self, other: &Snr) -> 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 Snr

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

fn partial_cmp(&self, other: &Snr) -> 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.
