Enum CauseParseError 

pub enum CauseParseError {
    Empty,
    BadHashLength {
        got: usize,
        expected: usize,
    },
    NonHexChar {
        ch: char,
        position: usize,
    },
    UppercaseHex {
        ch: char,
        position: usize,
    },
    BadStoreId(StoreIdError),
    TooManySeparators {
        count: usize,
        input: String,
    },
}

Why a cause reference was refused.

Every variant carries what was actually seen. A parser that says only “invalid” forces the operator to reconstruct the input by hand, and the inputs here are 64-character hex strings where the difference between valid and invalid is one character in the middle.

Variants

Empty

Empty input.

BadHashLength

Hash is not exactly 64 characters.

Fields

got: usize

expected: usize

NonHexChar

Hash contains a character that is not a hex digit.

Fields

ch: char

position: usize

UppercaseHex

Hash contains uppercase hex. Refused rather than lowercased — see the module docs on why content addressing gets one spelling.

Fields

ch: char

position: usize

BadStoreId(StoreIdError)

The store half of a qualified reference is not a valid store id.

TooManySeparators

More than one SEPARATOR, so the split point is a guess.

Fields

count: usize

input: String

Trait Implementations

impl Clone for CauseParseError

fn clone(&self) -> CauseParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CauseParseError

impl Eq for CauseParseError

impl Error for CauseParseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

fn from(e: StoreIdError) -> Self

Converts to this type from the input type.

impl PartialEq for CauseParseError

fn eq(&self, other: &CauseParseError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
