Struct Cp437Error

pub struct Cp437Error {
    pub representable_up_to: usize,
}

Errors which can occur when attempting to interpret a string as a sequence of cp437 codepoints.

As such, the into_cp437 family of functions and functions make use of this error, for example.

Fields

representable_up_to: usize

Returns the index in the given string up to which valid cp437 was verified.

It is the maximum index such that input[..index].to_cp_437() would return Ok(_).

Examples

// some unrepresentable characters, in a &str
let word = "Eżektor";

// ToCp437::to_cp437() returns a Cp437Error
let error = word.to_cp437(&CP437_CONTROL).unwrap_err();

// the second character is unrepresentable here
assert_eq!(error.representable_up_to, 1);

Trait Implementations

impl Clone for Cp437Error

fn clone(&self) -> Cp437Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cp437Error

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

Formats the value using the given formatter.

impl Hash for Cp437Error

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 Cp437Error

fn cmp(&self, other: &Cp437Error) -> 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 Cp437Error

fn eq(&self, other: &Cp437Error) -> 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 Cp437Error

fn partial_cmp(&self, other: &Cp437Error) -> 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.
