Struct ValidationContext

pub struct ValidationContext<'a> {
    pub arena: &'a Bump,
    pub errors: Vec<'a, &'a str>,
}

The ValidationContext carrying a reference to the AST Context’s arena and a list of errors.

New errors are added to the list as validation continues to issue error messages if validation has failed on a document.

Fields

arena: &'a Bump

errors: Vec<'a, &'a str>

Implementations

impl<'a> ValidationContext<'a>

pub fn new(ctx: &'a ASTContext) -> Self

Create a new ValidationContext given an AST Context.

pub fn add_error<S: AsRef<str>>(&mut self, str: S)

Add an error to the list of errors in the ValidationContext.

This is called inside of validation rules to add an error to the list and fail validation of the currently validating document.

pub fn to_result(self) -> Result<(), Error>

Convert the context into a result which carries an error if validation has failed on the current document.

This is used by ValidateNode and the ValidationRule’s validate method to convert the context into a result.
