Implementations

impl LoraBandwidth

pub const fn code(self) -> u8

Returns the Bw bits.

Returns

The four bit code, 0 to 9.

pub const fn hz(self) -> u32

Returns the bandwidth in hertz, rounded to the nearest hertz.

Returns

The bandwidth: 500 kHz halved, or 125 kHz divided by 3 and halved, as many times as the setting takes.

pub fn from_hz(hz: u32) -> Option<LoraBandwidth>

Finds the setting for a bandwidth in hertz.

Arguments

• hz - the bandwidth in hertz, within 1% of one the chip supports.

Returns

The setting, or None for a bandwidth the SX127x does not offer.

pub const fn in_band(self, frequency_hz: u32) -> bool

Reports whether the bandwidth is available at a carrier frequency.

Arguments

• frequency_hz - the carrier frequency in hertz.

Returns

false for 250 and 500 kHz at or below LOW_BAND_TOP_HZ, which the datasheet excludes in the lowest band, and true otherwise.

Trait Implementations

impl Clone for LoraBandwidth

fn clone(&self) -> LoraBandwidth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LoraBandwidth

impl Debug for LoraBandwidth

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

Formats the value using the given formatter.

impl Eq for LoraBandwidth

impl Hash for LoraBandwidth

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 LoraBandwidth

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