Struct ConfigErrors 

pub struct ConfigErrors(pub NonEmptyVec<ConfigError>);

A non-empty collection of configuration errors.

Uses NonEmptyVec from stillwater to guarantee at least one error exists. This prevents the “empty error list” anti-pattern and enables safe first().

Tuple Fields

0: NonEmptyVec<ConfigError>

Implementations

impl ConfigErrors

pub fn single(error: ConfigError) -> Self

Create from a single error.

pub fn from_nonempty(errors: NonEmptyVec<ConfigError>) -> Self

Create from a non-empty vec.

pub fn from_vec(errors: Vec<ConfigError>) -> Option<Self>

Try to create from a vec, returning None if empty.

pub fn first(&self) -> &ConfigError

Get the first error (always exists).

pub fn as_slice(&self) -> Vec<&ConfigError>

Get all errors as a slice.

pub fn len(&self) -> usize

Number of errors.

pub fn is_empty(&self) -> bool

Check if empty (always false, but required for API consistency).

pub fn iter(&self) -> impl Iterator<Item = &ConfigError>

Iterate over errors.

pub fn with_context(self, context: impl Into<String>) -> Self

Add context to all errors.

pub fn with_path_prefix(self, prefix: &str) -> Self

Add a path prefix to all error paths.

This is used for nested validation to add parent context to error paths. For example, if an error has path “port” and prefix is “database”, the resulting path will be “database.port”.

impl ConfigErrors

pub fn pretty_print(&self, options: &PrettyPrintOptions)

Pretty print errors to stderr.

Stillwater Integration

ConfigErrors wraps NonEmptyVec<ConfigError>, guaranteeing at least one error exists. This eliminates empty-error-list edge cases.

pub fn format(&self, options: &PrettyPrintOptions) -> String

Pretty print to a string (for testing).

pub fn pretty_print_default(&self)

Pretty print with default options.
