Set the rounding mode for writing digits with precision control.
sourcepub const fn trim_floats(self, trim_floats: bool) -> OptionsBuilder
pub const fn trim_floats(self, trim_floats: bool) -> OptionsBuilder
Set if we should trim a trailing ".0"
from floats.
sourcepub const fn exponent(self, exponent: u8) -> OptionsBuilder
pub const fn exponent(self, exponent: u8) -> OptionsBuilder
Set the character to designate the exponent component of a float.
sourcepub const fn decimal_point(self, decimal_point: u8) -> OptionsBuilder
pub const fn decimal_point(self, decimal_point: u8) -> OptionsBuilder

self,
nan_string: Option<&'static [u8]>,
) -> OptionsBuilder
pub const fn nan_string( self, nan_string: Option<&'static [u8]>, ) -> OptionsBuilder
Set the string representation for NaN
.
Panics
Setting a value too large may cause a panic even if FORMATTED_SIZE
elements are provided.
sourcepub const fn inf_string(
self,
inf_string: Option<&'static [u8]>,
) -> OptionsBuilder
pub const fn inf_string( self, inf_string: Option<&'static [u8]>, ) -> OptionsBuilder
Set the string representation for Infinity
.
Panics
Setting a value too large may cause a panic even if FORMATTED_SIZE
elements are provided.
sourcepub const fn nan_str_is_valid(&self) -> bool
pub const fn nan_str_is_valid(&self) -> bool
Determine if nan_str
is valid.
sourcepub const fn inf_str_is_valid(&self) -> bool
pub const fn inf_str_is_valid(&self) -> bool
Determine if inf_str
is valid.
sourcepub const fn build_unchecked(&self) -> Options
pub const fn build_unchecked(&self) -> Options
Build the Options struct without validation.
§Panics
This is completely safe, however, misusing this, especially
the nan_string
and inf_string
representations could cause
panics at runtime. Always use [MAX_SPECIAL_STRING_LENGTH
] and
check if Self::is_valid
prior to using a created format string.
