Struct NodeFilter 

pub struct NodeFilter {
    pub types: Option<String>,
    pub min_traversal_successors: Option<i64>,
    pub max_traversal_successors: Option<i64>,
}

Represents various criteria that make a given node “valid”. A node is only valid if all the subcriteria present in this message are fulfilled.

Fields

types: Option<String>

Node restriction string. (e.g. “dir,cnt,rev”). Defaults to “*” (all).

min_traversal_successors: Option<i64>

Minimum number of successors encountered during the traversal. Default: no constraint

max_traversal_successors: Option<i64>

Maximum number of successors encountered during the traversal. Default: no constraint

Implementations

impl NodeFilter

pub fn types(&self) -> &str

Returns the value of types, or the default value if types is unset.

pub fn min_traversal_successors(&self) -> i64

Returns the value of min_traversal_successors, or the default value if min_traversal_successors is unset.

pub fn max_traversal_successors(&self) -> i64

Returns the value of max_traversal_successors, or the default value if max_traversal_successors is unset.

Trait Implementations

impl Clone for NodeFilter

fn clone(&self) -> NodeFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeFilter

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

Formats the value using the given formatter.

impl Default for NodeFilter

fn default() -> Self

Returns the “default value” for a type.

impl Message for NodeFilter

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for NodeFilter

fn eq(&self, other: &NodeFilter) -> 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.
