Enum PromptError 

#[non_exhaustive]
pub enum PromptError {
    MissingVariable(String),
    MissingField(&'static str),
    InvalidVersion {
        version: String,
        source: Error,
    },
    AlreadyRegistered {
        name: String,
        version: Version,
    },
    NotFound {
        name: String,
        version: Version,
    },
    NameNotFound(String),
}

Errors returned by prompt rendering, construction, and registry lookup.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingVariable(String)

A named variable required by the template was absent from the render context.

MissingField(&'static str)

A builder was missing a required field.

InvalidVersion

A prompt version string was not valid semver.

Fields

version: String

Supplied version.

source: Error

Parse failure.

AlreadyRegistered

A registry entry already exists.

Fields

name: String

Prompt name.

version: Version

Prompt version.

NotFound

A registry entry was not found.

Fields

name: String

Prompt name.

version: Version

Prompt version.

NameNotFound(String)

No versions exist for a prompt name.

Trait Implementations

impl Debug for PromptError

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

Formats the value using the given formatter.

impl Display for PromptError

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

Formats the value using the given formatter.

impl Error for PromptError

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>)
