Enum SecretError 

pub enum SecretError {
    FileNotFound(PathBuf),
    Io {
        path: PathBuf,
        source: Error,
    },
    InvalidSyntax {
        path: PathBuf,
        line: usize,
        message: String,
    },
}

Errors that can occur while loading secrets from a source.

These errors are typically encountered when loading a .env file via crate::EnvFileSource. Use pattern matching to distinguish between missing files, I/O errors, and parse errors.

Variants

FileNotFound(PathBuf)

The .env file path was explicitly provided but does not exist.

This error is returned by crate::EnvFileSource::load when the file is not found. Use crate::EnvFileSource::load_optional instead if the file is allowed to be absent.

Io

An I/O error occurred while reading the file.

This wraps the underlying filesystem error. Common causes include permission denied, invalid path, or disk read failures.

Fields

path: PathBuf

Path to the file that caused the error.

source: Error

Underlying I/O error from the filesystem.

InvalidSyntax

A line in the file could not be parsed as KEY=VALUE.

The syntax is described in crate::EnvFileSource. This error includes the exact line number (1-based) and a diagnostic message.

Fields

path: PathBuf

Path to the file that caused the error.

line: usize

1-based line number where the syntax error occurred.

message: String

Description of the syntax problem (e.g. “expected KEY=VALUE, got ...”).

Trait Implementations

impl Debug for SecretError

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

Formats the value using the given formatter.

impl Display for SecretError

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

Formats the value using the given formatter.

impl Error for SecretError

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.
