Implementations

impl Ledger

pub fn open(opening: OpeningLedger) -> Result<Self>

Opens a reusable package ledger after confirming the package policy has a session balance.

pub fn package_id(&self) -> &Id

Returns the package id value used by training assignment, progress, package, or parent-summary review.

pub fn entries(&self) -> &[LedgerEntry]

Returns the entries value used by training assignment, progress, package, or parent-summary review.

pub fn balance(&self) -> SessionBalance

Returns the balance value used by training assignment, progress, package, or parent-summary review.

Trait Implementations

impl Clone for Ledger

fn clone(&self) -> Ledger

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ledger

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Ledger

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Ledger

fn eq(&self, other: &Ledger) -> 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 Ledger

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
