Struct DescriptorValidator 

pub struct DescriptorValidator { /* private fields */ }

Validator for message descriptors.

Ensures that descriptors only reference regions with policies that are safe for zero-copy message passing (Immutable or AppendOnly).

Implementations

impl DescriptorValidator

pub const fn new() -> Self

Create a new validator with default settings (Immutable and AppendOnly allowed).

pub const fn immutable_only() -> Self

Create a validator that only allows Immutable regions.

pub fn validate_policy(&self, policy: &RegionPolicy) -> Result<()>

Validate that a region policy is safe for descriptor-based messaging.

Errors

Returns InvalidDescriptorRegion if the policy doesn’t allow descriptors.

pub fn validate_bounds( &self, descriptor: &MessageDescriptor, region_size: usize, ) -> Result<()>

Validate a descriptor against region bounds.

Arguments

• descriptor - The descriptor to validate
• region_size - The total size of the region

Errors

Returns InvalidParameter if the descriptor references memory outside the region.

pub fn validate( &self, descriptor: &MessageDescriptor, policy: &RegionPolicy, region_size: usize, ) -> Result<()>

Full validation of a descriptor.

Checks that:

1. The descriptor is valid (non-null region, non-zero length)
2. The region policy allows descriptors
3. The offset + length is within region bounds

Trait Implementations

impl Default for DescriptorValidator

fn default() -> Self

Returns the “default value” for a type.
