Enum ConfigError 

pub enum ConfigError {
    Env(VarError),
    NotFound {
        path: PathBuf,
    },
    Io {
        path: PathBuf,
        error: Error,
    },
    Parse {
        path: PathBuf,
        error: Box<dyn Error + Send + Sync + 'static>,
    },
    ParseDisabled {
        path: PathBuf,
    },
}

Error returned from various methods of Config.

Variants

Env(VarError)

The loading method expected CARGO_MANIFEST_DIR to be set and it wasn’t.

This is necessary to locate the root of the crate currently being compiled.

See the “Environment Variables” page of the Cargo Book for details.

NotFound

No configuration file was found. Not necessarily fatal.

Fields

path: PathBuf

Io

An I/O error occurred while attempting to read the config file at path.

If the error is io::ErrorKind::NotFound, Self::NotFound is returned instead.

Fields

path: PathBuf

error: Error

Parse

An error in the TOML was encountered while parsing the config file at path.

The error gives line numbers and context when printed with Display/ToString.

Only returned if the sqlx-toml feature is enabled.

Fields

path: PathBuf

error: Box<dyn Error + Send + Sync + 'static>

Type-erased [toml::de::Error].

ParseDisabled

A sqlx.toml file was found or specified, but the sqlx-toml feature is not enabled.

Fields

path: PathBuf

Implementations

impl ConfigError

pub fn from_io(path: impl Into<PathBuf>, error: Error) -> Self

Create a ConfigError from a std::io::Error.

Maps to either NotFound or Io.

pub fn not_found_path(&self) -> Option<&Path>

If this error means the file was not found, return the path that was attempted.

Trait Implementations

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Error for ConfigError

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<ConfigError> for Error

fn from(source: ConfigError) -> Self

Converts to this type from the input type.

impl From<VarError> for ConfigError

fn from(source: VarError) -> Self

Converts to this type from the input type.
