Struct Menu 

pub struct Menu<'a> {
    pub more: bool,
    pub choice_nb: u8,
    pub title: Text<'a>,
    pub subtitle: Text<'a>,
    pub bottom: Text<'a>,
    pub choices: Vec<Text<'a>>,
}

menu() object (Table 49) and list() object (Table 51) share this layout: choice_nb / item_nb, three header TEXT()s, then the choice/item TEXT()s.

Menu::more selects the _last vs _more tag and is set from the parsed tag. 0xFF for the count means “count not carried; read to end of object”.

Fields

more: bool

true = _more tag (more APDUs follow); false = _last.

choice_nb: u8

choice_nb / item_nb — 0xFF means the count is not carried on the wire.

title: Text<'a>

Title TEXT().

subtitle: Text<'a>

Sub-title TEXT().

bottom: Text<'a>

Bottom-line TEXT().

choices: Vec<Text<'a>>

The per-choice / per-item TEXT()s, in wire order.

Implementations

impl<'a> Menu<'a>

pub fn menu_tag(&self) -> ApduTag

The menu apdu_tag for this object given Menu::more.

pub fn list_tag(&self) -> ApduTag

The list apdu_tag for this object given Menu::more (for use as a List).

pub fn parse_list(bytes: &'a [u8]) -> Result<Self>

Parse a list() object (Tables 51) from a complete APDU.

pub fn list_serialized_len(&self) -> usize

Serialized length of this object as a list() (identical to a menu).

pub fn serialize_list(&self, buf: &mut [u8]) -> Result<usize>

Serialize this object as a list() into buf.

Trait Implementations

impl<'a> ApduDef<'a> for Menu<'a>

const TAG: ApduTag = tag::MENU_LAST

The object’s 3-byte apdu_tag (EN 50221 Table 58).

const NAME: &'static str = "MENU"

Diagnostic name, SCREAMING_SNAKE, suffix-free: CA_PMT, PROFILE_ENQ, APPLICATION_INFO, DATE_TIME.

impl<'a> Clone for Menu<'a>

fn clone(&self) -> Menu<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Menu<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Menu<'a>

impl<'a> From<Menu<'a>> for AnyApdu<'a>

fn from(v: Menu<'a>) -> Self

Converts to this type from the input type.

impl<'a> Parse<'a> for Menu<'a>

type Error = Error

The error type this implementer returns. Typically the enclosing crate’s Error enum.

fn parse(bytes: &'a [u8]) -> Result<Self>

Parse bytes as Self. Returns Err(Self::Error) on any protocol violation or buffer underrun.

impl<'a> PartialEq for Menu<'a>

fn eq(&self, other: &Menu<'a>) -> 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<'a> Serialize for Menu<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Serialize for Menu<'_>

type Error = Error

The error type this implementer returns (usually the same as the corresponding Parse impl, but need not be).

fn serialized_len(&self) -> usize

Number of bytes serialize_into will write.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize>

Write the serialised form into buf. Returns the number of bytes written (always equal to serialized_len()).

fn to_bytes(&self) -> Vec<u8>

where Self::Error: Debug,

Convenience: allocate a Vec and serialise into it.
