Struct ParseError 

pub struct ParseError(pub String);

A string failed to parse into a typed variant (model ID, ChatKey, etc.).

The public String field contains the human-readable error message produced during parsing.

This type is used as the Err for FromStr on Model, AliasedModel, and Provider.

Example

use std::str::FromStr;
use crate::model::Model;
use crate::error::ParseError;

let result = Model::from_str("invalid-format");
assert!(matches!(result, Err(ParseError(_))));

if let Err(ParseError(msg)) = result {
    eprintln!("parse failed: {msg}");
}

Implementations

impl ParseError

pub fn new(msg: impl Into<String>) -> Self

Construct a ParseError with the given message.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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.
