Function validate_page_size 

pub fn validate_page_size(size: Option<u32>) -> Result<u32, ValidationError>

Validates and normalizes a page size parameter.

This function ensures that page sizes are within safe bounds to prevent resource exhaustion attacks.

Behavior

• Returns DEFAULT_PAGE_SIZE if None is provided
• Rejects page size of 0
• Caps page size at MAX_PAGE_SIZE with warning log
• Returns the validated page size

Returns

A Result containing the validated page size or a ValidationError.

Security

Errors

Returns an error if the API request fails, the resource is not found, or authentication/authorization fails. This function prevents DoS attacks from unbounded pagination requests.

Examples

use veracode_platform::validation::{validate_page_size, DEFAULT_PAGE_SIZE, MAX_PAGE_SIZE};

// Default when None
assert_eq!(validate_page_size(None).unwrap(), DEFAULT_PAGE_SIZE);

// Normal value passes through
assert_eq!(validate_page_size(Some(100)).unwrap(), 100);

// Zero is rejected
assert!(validate_page_size(Some(0)).is_err());

// Too large is capped (with warning log)
assert_eq!(validate_page_size(Some(10000)).unwrap(), MAX_PAGE_SIZE);

Errors

Returns an error if validation fails due to invalid input parameters.
