pub struct EnvArg { /* private fields */ }

An ink! environment argument.

Implementations

impl EnvArg

pub fn can_cast(arg: &InkArg) -> bool

Returns true if the ink! argument can be converted into an ink! environment argument.

pub fn cast(arg: InkArg) -> Option<Self>

Converts an ink! attribute argument into an inK! environment argument.

pub fn arg(&self) -> &InkArg

Returns the ink! attribute argument for ink! environment.

pub fn is_path(&self) -> bool

Returns true if the value is a path.

pub fn as_path_with_inaccurate_text_range(&self) -> Option<Path>

Converts the value if it’s an integer literal (decimal or hexadecimal) into a u32.

pub fn text_range(&self) -> TextRange

Returns the text range of the ink! environment argument.

Trait Implementations

impl Clone for EnvArg

fn clone(&self) -> EnvArg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnvArg

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

Formats the value using the given formatter.

impl PartialEq for EnvArg

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