Struct mycelium_command::Command

pub struct Command {
    pub action: Action,
    pub limit: Option<Limits>,
    pub ops: Vec<(LogicOp, What)>,
    pub tag: String,
    pub what: What,
}

Command struct can be used to build a command with the normal builder pattern.

use crate::mycelium_command::prelude::*;
let cmd = Command::new()
    .with_action(Action::Select)
    .with_what(What::Index(String::from("dog"))) //and
    .with_or_what(What::Index("idx3".to_string())) //or
    .with_limit(Limits::First(4)); // first usize results

• Action: Default (error), Archive, Insert, Select, Update. Action to perform.
• Limits: None, Some(Default), Some(First(usize)), Some(Last(usize)), Some(Limit(usize))
• LogicOps: List of logic ops and target
• Tag: Tag to execute command against. Required.
• What: What to execute command or operation against. Id of another node, Index value, or other tags.

Fields

action: Action

limit: Option<Limits>

ops: Vec<(LogicOp, What)>

tag: String

what: What
