Struct TimeLogValidator 

pub struct TimeLogValidator {
    validators: Vec<Box<dyn Validator>>,
}

The main validator that runs all validators. Add the other validators to this one with TimeLogValidator::with_validator, then call TimeLogValidator::validate to run the validation.

Example

let time_logs = [
    TimeLog{ summary: None, ..Default::default() },
    TimeLog{ summary: Some("Code Review".to_string()), ..Default::default() }
];

let mut validator = TimeLogValidator::new()
    .with_validator(ExcessiveHoursValidator::new(10))
    .with_validator(HasSummaryValidator);
let results = validator.validate(&time_logs);

// Assertions to check the results, you don't need to do this in your code
assert!(results[0].has_problems(&ValidationProblem::MissingSummary));
assert!(!results[0].has_problems(&ValidationProblem::ExcessiveHours{ max_hours: 10 }));
assert!(results[1].is_valid());

for result in results {
    if result.is_valid() { continue; }
    for problem in &result.problems {
        match problem {
            ValidationProblem::ExcessiveHours { max_hours } => println!("Time spent exceeds maximum of {max_hours} hours"),
            ValidationProblem::MissingSummary => println!("No summary was entered"),
            _ => {}
        }
    }
}

Implementations

impl TimeLogValidator

pub fn new() -> Self

Create a new TimeLogValidator.

pub fn with_validator(self, validator: impl Validator + 'static) -> Self

Add a new validator to the chain. See Validator for more information.

Example

let mut validator = TimeLogValidator::new()
    .with_validator(ExcessiveHoursValidator::new(10))
    .with_validator(HasSummaryValidator);

pub fn validate<'a>( &mut self, time_logs: &'a [TimeLog], ) -> Vec<ValidationResult<'a>>

Run all validators on the given time logs.

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.
