Struct ChipRevision 

pub struct ChipRevision {
    pub major: u8,
    pub minor: u8,
}

Represents the hardware revision.

The type supports converting between two separate u16-based representations:

• Combined: a u16 calculated as major * 100 + minor. The combined representation is more often used by ESP-IDF, and working with it involves integer division. Note that the combined representation assumes minor is less than 100.
• Packed: a u16 with the major revision in the high byte and the minor revision in the low byte.

Examples

use esp_hal::efuse::ChipRevision;

let rev = esp_hal::efuse::chip_revision();
println!("Chip revision: {}.{}", rev.major, rev.minor);

// You can compare against other ChipRevision objects
if rev < ChipRevision::from_combined(300) {
    // You can print a debug representation
    println!("Chip revision is too old: {:?}", rev);
}
if rev >= ChipRevision::from_packed(0x400) {
    println!("Chip revision is too new: {:?}", rev);
}

// You can convert into two different numeric representations.
assert!(rev.packed() >= 0x300);
assert!(rev.combined() >= 300);

Fields

major: u8

The major revision number.

minor: u8

The minor revision number.

Implementations

impl ChipRevision

pub const fn from_combined(revision: u16) -> Self

Creates a new ChipRevision from a combined revision value.

pub const fn combined(self) -> u16

Returns the combined revision value as a u16.

The combined revision value is a u16 calculated as major * 100 + minor.

pub const fn from_packed(packed: u16) -> Self

Creates a new ChipRevision from a packed revision value.

The packed revision value is a u16 with the major revision in the high byte and the minor revision in the low byte.

pub const fn packed(self) -> u16

Returns the packed revision value as a u16.

The packed revision value is a u16 with the major revision in the high byte and the minor revision in the low byte.

Trait Implementations

impl Clone for ChipRevision

fn clone(&self) -> ChipRevision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChipRevision

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

Formats the value using the given formatter.

impl Hash for ChipRevision

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 Ord for ChipRevision

fn cmp(&self, other: &Self) -> 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 ChipRevision

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

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