Implementations

impl ChildNumber

pub fn from_normal_idx(index: u32) -> Result<ChildNumber, Error>

Create a Normal from an index, returns an error if the index is not within [0, 2^31 - 1].

pub fn from_hardened_idx(index: u32) -> Result<ChildNumber, Error>

Create a Hardened from an index, returns an error if the index is not within [0, 2^31 - 1].

pub fn is_normal(&self) -> bool

Returns true if the child number is a Normal value.

pub fn is_hardened(&self) -> bool

Returns true if the child number is a Hardened value.

pub fn increment(self) -> Result<ChildNumber, Error>

Returns the child number that is a single increment from this one.

Trait Implementations

impl AsRef<[ChildNumber]> for ChildNumber

fn as_ref(&self) -> &[ChildNumber]

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

Formats the value using the given formatter.

impl From<ChildNumber> for u32

fn from(cnum: ChildNumber) -> u32

Converts to this type from the input type.

impl From<u32> for ChildNumber

fn from(number: u32) -> ChildNumber

Converts to this type from the input type.

impl FromIterator<ChildNumber> for DerivationPath

fn from_iter<T>(iter: T) -> DerivationPath

where T: IntoIterator<Item = ChildNumber>,

Creates a value from an iterator.

impl FromStr for ChildNumber

type Err = Error

The associated error which can be returned from parsing.

fn from_str(inp: &str) -> Result<ChildNumber, Error>

Parses a string s to return a value of this type.

impl Hash for ChildNumber

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 ChildNumber

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

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