Struct holmes::engine::types::Predicate

pub struct Predicate {
    pub name: String,
    pub description: Option<String>,
    pub fields: Vec<Field>,
}

A Predicate is a name combined with a list of typed slots, e.g.

foo(uint64, string)

would be represented as

use holmes::pg::dyn::types;
use holmes::engine::types::{Predicate, Field};
use std::sync::Arc;
Predicate {
    name: "foo".to_string(),
    description: None,
    fields: vec![Field {
        name: None,
        description: None,
        type_: Arc::new(types::UInt64)
    }, Field {
        name: None,
        description: None,
        type_: Arc::new(types::String)
    }]
};

Trait Implementations

impl PartialEq for Predicate

fn eq(&self, __arg_0: &Predicate) -> bool

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

fn ne(&self, __arg_0: &Predicate) -> bool

This method tests for !=.

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Predicate

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

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

Feeds a slice of this type into the given [Hasher].
