Struct HistoryEntry 

pub struct HistoryEntry {
    pub entry_uuid: Uuid,
    pub expression: Token,
    /* private fields */
}

Individual history entry retaining it’s UUID, parser tokens, and textual rendition.

Fields

entry_uuid: Uuid

UUID of the entry.

expression: Token

Parser tokens of the entry, basically the entire expression parsed down into it’s most basic form

Implementations

impl HistoryEntry

pub fn new(expression: &Token, session: &Session) -> Self

Creates a new entry struct from parser tokens and the desired amount of decimal places to render.

pub fn to_string(&self) -> String

Converts the entry to a string.

pub fn only_equality(&self) -> &Token

Gets the entry with only the equality

pub fn render_without_equality(&self, session: &Session) -> String

Renders the entry without an equal sign, nor everything right of it.

Just returns the expression unmodified if there is no equal sign.

Trait Implementations

impl Clone for HistoryEntry

fn clone(&self) -> HistoryEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistoryEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HistoryEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HistoryEntry

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
