Enum Error 

pub enum Error {
    MissingFields {
        required_fields: Vec<MissingField<'static>>,
    },
    ParseIntError(ParseIntError),
    InconsistentSetting {
        first_source: String,
        first_setting: String,
        second_source: String,
        second_setting: String,
    },
    ParseFieldError {
        field_name: &'static str,
        field_type: &'static str,
        error_condition: Box<dyn Error + Send + Sync>,
    },
    FileReadError(FileReadError),
}

All possible things that can go wrong when using partial_config.

Variants

MissingFields

Some of the required fields are missing

Fields

required_fields: Vec<MissingField<'static>>

ParseIntError(ParseIntError)

A field that is supposed to be a number failed to be parsed from a string. Provided for convenience.

InconsistentSetting

A single setting was specified in two layers, and the two do not agree. This is useful in cases where you want to debug a sticky setting that is strictly not supposed to be set, but is. It is also used for different aliases in the EnvSourced infrastructure of this crate.

Fields

first_source: String

first_setting: String

second_source: String

second_setting: String

ParseFieldError

The field failed to parse. This is a more generic, and therefore less useful version of the other errors. Consider creating your own error type if you plan to do anything other than print the error message after this point.

Fields

field_name: &'static str

field_type: &'static str

error_condition: Box<dyn Error + Send + Sync>

FileReadError(FileReadError)

The file failed to read.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<FileReadError> for Error

Available on crate feature serde only.

fn from(value: FileReadError) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for Error

fn from(value: ParseIntError) -> Self

Converts to this type from the input type.
