Enum google_fonts::error::FontError

pub enum FontError {
    Network(Error),
    Deserialize(Error),
    CacheDir(StringError),
    CacheFile(Error),
}

An error that can occur while using the google-fonts crate.

This enum represents various errors that can be encountered while downloading, deserializing, caching, or otherwise handling fonts from Google Fonts. Each variant corresponds to a specific type of error that can occur during the process.

Variants

• Network: Indicates an error that occurred while making a network request.
• Deserialize: Indicates an error that occurred while deserializing JSON data.
• CacheDir: Indicates an error that occurred while interacting with the cache directory.
• CacheFile: Indicates an error that occurred while interacting with a cache file.

Variants

Network(Error)

An error that occurred while making a network request.

This variant wraps a reqwest::Error, which provides more details about the specific network-related error that occurred.

Example

use google_fonts::FontError;
if let FontError::Network(e) = error {
    println!("Network error: {}", e);
}

Deserialize(Error)

An error that occurred while deserializing JSON data.

This variant wraps a serde_json::Error, which provides more details about the specific deserialization error that occurred.

Example

use google_fonts::FontError;
if let FontError::Deserialize(e) = error {
    println!("Deserialization error: {}", e);
}

CacheDir(StringError)

An error that occurred while interacting with the cache directory.

This variant wraps a StringError, which provides more details about the specific error related to the cache directory.

Example

use google_fonts::FontError;
if let FontError::CacheDir(e) = error {
    println!("Cache directory error: {}", e);
}

CacheFile(Error)

An error that occurred while interacting with a cache file.

This variant wraps a std::io::Error, which provides more details about the specific I/O error that occurred.

Example

use google_fonts::FontError;
if let FontError::CacheFile(e) = error {
    println!("Cache file error: {}", e);
}

Trait Implementations

impl Debug for FontError

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

Formats the value using the given formatter.

impl Display for FontError

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

Formats the value using the given formatter.

impl Error for FontError

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

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.
