Enum ParserError

pub enum ParserError {
    InvalidFileFormat(String),
    MissingField(String),
    TypeMismatch {
        field: String,
        expected: String,
    },
    MissingFileExtension,
    NestedError {
        section: String,
        source: Box<ParserError>,
    },
    Io(Error),
    TomlError(TomlError),
    JsonError(Error),
    YmlError(ScanError),
}

Represents various errors that can occur during the parsing process. Leverages the thiserror crate for structured and user-friendly error handling.

Variants

InvalidFileFormat(String)

Indicates that the provided file format is unsupported. Occurs when trying to parse a file with an invalid or unrecognized extension.

MissingField(String)

Triggered when a required field is missing in the configuration file. This happens when an expected field is absent.

TypeMismatch

Occurs when there is a type mismatch in a field within the configuration file. This happens when a field’s value type does not match the expected type.

Fields

field: String

expected: String

MissingFileExtension

Raised when a file path lacks an extension. Without an extension, determining the file format becomes impossible.

NestedError

Indicates a nested configuration error in a specific section. Provides details about the section and the root cause of the error.

Fields

section: String

source: Box<ParserError>

Io(Error)

Reflects standard IO errors encountered during file operations. Arises when issues occur while reading or writing files.

TomlError(TomlError)

Represents a failure in parsing a TOML file. Occurs when the parser encounters invalid TOML syntax or structure.

JsonError(Error)

Represents a failure in parsing a JSON file. Triggered by invalid JSON syntax or structure during parsing.

YmlError(ScanError)

Represents a failure in parsing a YAML file. Triggered by invalid YAML syntax or structure during parsing.

Trait Implementations

impl Debug for ParserError

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

Formats the value using the given formatter.

impl Display for ParserError

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

Formats the value using the given formatter.

impl Error for ParserError

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.
