Enum EnvInventoryError 

pub enum EnvInventoryError {
    ReadFileError(String),
    ParseFileError(String),
    MissingEnvVars(Vec<String>),
    MissingEnvVar(String),
}

Represents the potential errors that can be encountered by the env-inventory module.

This enum provides specific error variants to handle different failure scenarios when working with environment variable loading and validation in the env-inventory module. It is designed to give users of the module clear feedback on the nature of the error encountered.

Variants

• ReadFileError: Occurs when there’s an issue reading a settings file.
• ParseFileError: Occurs when parsing a settings file fails, possibly due to a malformed structure.
• MissingEnvVars: Occurs when one or more registered environment variables are not present in either the environment or the settings files.

Examples

fn read_settings(file_path: &str) -> Result<(), EnvInventoryError> {
    if fs::read(file_path).is_err() {
        return Err(EnvInventoryError::ReadFileError(file_path.to_string()));
    }
    // ... Additional logic ...
    Ok(())
}

Variants

ReadFileError(String)

Represents a failure to read a settings file.

Contains a string that provides the path to the file that failed to be read.

ParseFileError(String)

Represents a failure to parse a settings file.

Contains a string that provides the path to the file that failed to be parsed.

MissingEnvVars(Vec<String>)

Represents the absence of required environment variables.

Contains a vector of strings, each representing a missing environment variable.

MissingEnvVar(String)

Represents the absence of required environment variables. variable.

Trait Implementations

impl Debug for EnvInventoryError

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

Formats the value using the given formatter.

impl Display for EnvInventoryError

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