Struct FlowSpecRule 

pub struct FlowSpecRule {
    pub components: Vec<FlowSpecComponent>,
}

A complete FlowSpec NLRI rule — an ordered set of match components.

Components must be sorted by ascending type code. A rule may contain at most one component of each type.

Fields

components: Vec<FlowSpecComponent>

Ordered match components (ascending type code).

Implementations

impl FlowSpecRule

pub fn validate(&self) -> Result<(), DecodeError>

Validate that components are in ascending type-code order.

Errors

Returns DecodeError if the rule has no components or if components are not in strictly ascending type-code order.

pub fn encoded_len(&self, afi: Afi) -> usize

Return this rule’s encoded FlowSpec NLRI payload length, excluding the one- or two-byte FlowSpec rule length prefix.

pub fn validate_encoded_len(&self, afi: Afi) -> Result<(), EncodeError>

Validate that this rule can be represented by FlowSpec’s 12-bit rule length field.

Errors

Returns EncodeError if the encoded rule exceeds 4095 bytes.

pub fn display_string(&self) -> String

Return a human-readable display string for logging / gRPC.

pub fn destination_prefix(&self) -> Option<Prefix>

Extract the destination prefix from the rule, if present.

Trait Implementations

impl Clone for FlowSpecRule

fn clone(&self) -> FlowSpecRule

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FlowSpecRule

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

Formats the value using the given formatter.

impl Display for FlowSpecRule

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

Formats the value using the given formatter.

impl Eq for FlowSpecRule

impl Hash for FlowSpecRule

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for FlowSpecRule

fn cmp(&self, other: &FlowSpecRule) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FlowSpecRule

fn eq(&self, other: &FlowSpecRule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for FlowSpecRule

fn partial_cmp(&self, other: &FlowSpecRule) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
