Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Hash

“hash”

the point hash e.g. [b:AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA] ( implies DATA)

Group

“group”

group id e.g. [#:pub] ( implies LINK)

Domain

“domain”

domain - if fewer than 16 bytes, prepadded with e.g. [a:example] ( implies LINK)

Prefix

“prefix”

all points with spacename starting with prefix - only accepts ‘=’ op e.g. /hello/world ( implies LINK)

Spacename

“spacename”

exact spacename - only accepts ‘=’ op e.g. /hello/world ( implies LINK)

Pubkey

“pubkey”

public key used to sign point e.g. [@:me:local] ( implies SIGNATURE)

Create

“create”

the create stamp e.g. [now:-1H] ( implies LINK)

Depth

“depth”

the total number of space components - max 8 e.g. [u8:0] ( implies LINK)

LinksLen

“links_len”

the number of links in a packet e.g. [u16:0] ( implies LINK)

DataSize

“data_size”

the byte size of the data field e.g. [u16:0] ( implies LINK)

Recv

“recv”

the recv time of a packet e.g. [now:+1D] ( implies DATA)

IBranch

“i_branch”

total packets per uniq (group,domain,space,key) - only applicable during local tree index, ignored otherwise e.g. [u32:0] ( implies LINK)

IDb

“i_db”

total packets read from local instance e.g. [u32:0] ( implies EMPTY)

INew

“i_new”

total newly received packets e.g. [u32:0] ( implies EMPTY)

I

“i”

total matched packets e.g. [u32:0] ( implies EMPTY)

Hop

“hop”

(mutable) number of hops e.g. [u16:5] ( implies EMPTY)

Stamp

“stamp”

(mutable) variable stamp e.g. [now] ( implies EMPTY)

Ubits0

“ubits0”

(mutable) user defined bits e.g. [u32:0] ( implies EMPTY)

Ubits1

“ubits1”

(mutable) user defined bits e.g. [u32:0] ( implies EMPTY)

Ubits2

“ubits2”

(mutable) user defined bits e.g. [u32:0] ( implies EMPTY)

Ubits3

“ubits3”

(mutable) user defined bits e.g. [u32:0] ( implies EMPTY)

Type

“type”

the field type bits - implied by other predicates e.g. [b2:00000001] ( implies EMPTY)

Netflags

“netflags”

(mutable) netflags e.g. [b2:00000000] ( implies EMPTY)

Size

“size”

exact size of the netpkt when using lk_write or lk_read - includes netheader and hash e.g. [u16:4] ( implies DATA)

Implementations

impl PredicateType

pub const ALL: [PredicateType; 24] = _

pub fn try_from_id(id: &[u8]) -> Option<PredicateType>

pub const fn info(self) -> PredInfo

Trait Implementations

impl Clone for PredicateType

fn clone(&self) -> PredicateType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PredicateType

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

Formats the value using the given formatter.

impl Display for PredicateType

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

Formats the value using the given formatter.

impl FromStr for PredicateType

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<PredicateType, <PredicateType as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq<PredicateType> for PredicateType

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

This method tests for self and other values to be equal, and is used by ==.

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

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