Struct Info 

pub struct Info { /* private fields */ }

Metadata about a constructed QrCode, returned by QrCode::info.

Fields that require retaining the input data or the chosen mask (e.g. encoding_modes, mask_pattern, remaining_capacity) are intentionally omitted to keep QrCode zero-overhead; they may be added in a later version.

Implementations

impl Info

pub const fn version(&self) -> Version

The QR Version.

pub const fn ec_level(&self) -> EcLevel

The error correction level.

pub const fn width(&self) -> usize

Modules per side (excluding the quiet zone).

pub const fn module_count(&self) -> usize

Total number of modules (width * width).

pub const fn max_allowed_errors(&self) -> usize

Maximum number of erroneous modules that can still be recovered.

pub const fn data_capacity_bytes(&self) -> usize

Data capacity of this symbol in bytes.

Trait Implementations

impl Clone for Info

fn clone(&self) -> Info

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Info

impl Debug for Info

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

Formats the value using the given formatter.

impl Eq for Info

impl PartialEq for Info

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