Implementations

impl ECIStringBuilder

pub fn with_capacity(initial_capacity: usize) -> Self

pub fn bytes(&self) -> &[u8]

pub fn append_char(&mut self, value: char)

Appends {@code value} as a byte value

@param value character whose lowest byte is to be appended

pub fn append_byte(&mut self, value: u8)

Appends {@code value} as a byte value

@param value byte to append

pub fn append_bytes(&mut self, value: &[u8])

pub fn append_string(&mut self, value: &str)

Appends the characters in {@code value} as bytes values

@param value string to append

pub fn append(&mut self, value: i32)

Append the string repesentation of {@code value} (short for {@code append(String.valueOf(value))})

@param value int to append as a string

pub fn append_eci(&mut self, eci: Eci)

Appends ECI value to output.

@param value ECI value to append, as an int @throws FormatException on invalid ECI value

pub fn switch_encoding(&mut self, charset: CharacterSet, is_eci: bool)

Change the current encoding characterset, finding an eci to do so

pub fn encodeCurrentBytesIfAny(&self) -> String

Finishes encoding anything in the buffer using the current ECI and resets.

This function can panic

pub fn appendCharacters(&mut self, value: &str)

Appends the characters from {@code value} (unlike all other append methods of this class who append bytes)

@param value characters to append

pub fn len(&mut self) -> usize

Short for {@code toString().length()} (if possible, use {@link #isEmpty()} instead)

@return length of string representation in characters

pub fn reserve(&mut self, additional: usize)

Reserve an additional number of bytes for storage

pub fn is_empty(&mut self) -> bool

@return true iff nothing has been appended

pub fn build_result(self) -> Self

Trait Implementations

impl AddAssign<String> for ECIStringBuilder

fn add_assign(&mut self, rhs: String)

Performs the += operation.

impl AddAssign<u8> for ECIStringBuilder

fn add_assign(&mut self, rhs: u8)

Performs the += operation.

impl Clone for ECIStringBuilder

fn clone(&self) -> ECIStringBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ECIStringBuilder

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

Formats the value using the given formatter.

impl Default for ECIStringBuilder

fn default() -> ECIStringBuilder

Returns the “default value” for a type.

impl Display for ECIStringBuilder

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

Formats the value using the given formatter.

impl PartialEq<ECIStringBuilder> for ECIStringBuilder

fn eq(&self, other: &ECIStringBuilder) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
