Struct VarTable 

pub struct VarTable {
    pub variables: Vec<Variable>,
}

Struct for the built-in vartable type

Fields

variables: Vec<Variable>

Vector of variables

Implementations

impl VarTable

pub fn new() -> Self

Create an empty VarTable

pub fn merge(&mut self, vartable: &VarTable) -> Result<(), Box<dyn Error>>

Merge with another vartable, overwriting all existing variables with ones found in the other vartable

pub fn add(&mut self, var: Variable) -> Result<(), Box<dyn Error>>

Add a variable to the VarTable, fail if the variable exists

pub fn remove(&mut self, id: &str) -> Result<(), Box<dyn Error>>

Remove a variable from the VarTable given just the id, fail if the variable doesn’t exist

pub fn store(&mut self, var: Variable) -> Result<(), Box<dyn Error>>

Store a variable to the VarTable, replacing a variable if it exists with the updated value

pub fn get(&mut self, id: &str) -> Result<Variable, Box<dyn Error>>

Get a variable from the VarTable given just the id

Trait Implementations

impl Clone for VarTable

fn clone(&self) -> VarTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarTable

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VarTable

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VarTable

fn eq(&self, other: &VarTable) -> 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 Serialize for VarTable

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
