Struct ArgResult

pub struct ArgResult<T> {
    pub value: Option<T>,
    pub errors: Vec<Error>,
    pub location: Span,
}

A result type that can contain multiple errors and a value at the same time.

Fields

value: Option<T>

errors: Vec<Error>

location: Span

Implementations

impl<T> ArgResult<T>

pub fn new(location: Span) -> Self

pub fn add_error(&mut self, msg: ErrorMsg)

Adds an error using the stored Span.

pub fn add_value(&mut self, value: T)

Adds a value.

pub fn add_result(&mut self, value: Result<T, ErrorMsg>)

Adds a value or an error that uses the stored Span depending on the result variant.

pub fn is_found(&self) -> bool

pub fn found_with_errors(&self) -> bool

pub fn found_with_value(&self) -> bool

Trait Implementations

impl<T: Concat> Concat for ArgResult<T>

fn concat(&mut self, other: Self)

Combines an argument.

const NO_DUPLICATES: bool = true

Determines whether a duplicate is allowed or if an error should be thrown.
This logic is handled in the implementation for ArgResult.
Typically only true for primitive types.

impl<T: Debug> Debug for ArgResult<T>

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

Formats the value using the given formatter.
