pub struct RowValue { /* private fields */ }Expand description
A value from a database row.
This struct represents a single column value from a database row. It includes both the column name and the raw binary data for the value, which can be accessed or converted to other types as needed.
Implementations§
Source§impl RowValue
impl RowValue
Sourcepub fn bytes(&self) -> Option<&[u8]>
pub fn bytes(&self) -> Option<&[u8]>
Returns the raw binary data for this value.
§Returns
A slice of bytes if the value is not NULL, or None if the value is NULL.
Sourcepub fn into_bytes(self) -> Option<Vec<u8>>
pub fn into_bytes(self) -> Option<Vec<u8>>
Consumes the RowValue and returns the underlying raw binary data.
This method transfers ownership of the byte vector. If the value
is NULL, it returns None.
§Returns
An owned Vec<u8> if the value is not NULL, or None if the value is NULL.
Sourcepub fn as_str(&self) -> Result<Option<&str>, SdkError>
pub fn as_str(&self) -> Result<Option<&str>, SdkError>
This method attempts to interpret the binary data as a UTF-8 encoded string.
§Returns
Ok(Some(str))if the value is not NULL and was successfully converted to a stringOk(None)if the value is NULLErrwith a message if the value is not valid UTF-8
Sourcepub fn as_value<T>(&self) -> Result<Option<T>, SdkError>where
T: TryFromBytes,
pub fn as_value<T>(&self) -> Result<Option<T>, SdkError>where
T: TryFromBytes,
Converts the binary data to a value that implements TryFromBytes.
This method attempts to interpret the binary data as a value of the specified type. It’s particularly useful for converting database values to Rust values.
§Type Parameters
T- The type to convert the binary data to, must implementTryFromBytes
§Returns
Ok(Some(T))if the value is not NULL and was successfully convertedOk(None)if the value is NULLErrwith a message if conversion failed
Sourcepub fn as_json<T>(&self) -> Result<Option<T>, SdkError>where
T: for<'a> Deserialize<'a>,
pub fn as_json<T>(&self) -> Result<Option<T>, SdkError>where
T: for<'a> Deserialize<'a>,
Deserializes this value as JSON into the specified type.
This method parses the binary data as JSON and converts it to the requested type.
§Type Parameters
T- The type to deserialize the JSON into
§Returns
Ok(Some(T))if the value is not NULL and was successfully deserializedOk(None)if the value is NULLErrwith a message if deserialization failed

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
