Enum SettleError 

pub enum SettleError {
    PinsDiffer {
        first: String,
        first_ref: String,
        second: String,
        second_ref: String,
    },
    PinBesideRange {
        pinned_by: String,
        reference: String,
        ranged_by: String,
        range: VersionReq,
    },
}

Constraints that cannot both hold on one ref.

Variants

PinsDiffer

Fields

first: String

first_ref: String

second: String

second_ref: String

PinBesideRange

A pin names no version, so no range holds at it.

Fields

pinned_by: String

reference: String

ranged_by: String

range: VersionReq

Implementations

impl SettleError

pub fn code(&self) -> &'static str

A stable identifier for callers that map failures to their own codes.

Trait Implementations

impl Clone for SettleError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SettleError

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

Formats the value using the given formatter.

impl Display for SettleError

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

Formats the value using the given formatter.

impl Eq for SettleError

impl Error for SettleError

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.

impl From<SettleError> for ChooseError

fn from(source: SettleError) -> Self

Converts to this type from the input type.

impl PartialEq for SettleError

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

Equality operator ==.

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

Inequality operator !=.
