Implementations§
Source§impl Expression
impl Expression
Sourcepub fn new_string(value: String) -> Self
pub fn new_string(value: String) -> Self
Create an expression representing a literal string.
Sourcepub fn new_record(
fields: impl IntoIterator<Item = (String, Self)>,
) -> Result<Self, ExpressionConstructionError>
pub fn new_record( fields: impl IntoIterator<Item = (String, Self)>, ) -> Result<Self, ExpressionConstructionError>
Create an expression representing a record.
Error if any key appears two or more times in fields
.
Sourcepub fn new_set(values: impl IntoIterator<Item = Self>) -> Self
pub fn new_set(values: impl IntoIterator<Item = Self>) -> Self
Create an expression representing a Set.
Sourcepub fn new_ip(src: impl AsRef<str>) -> Self
pub fn new_ip(src: impl AsRef<str>) -> Self
Create an expression representing an ip address.
This function does not perform error checking on the source string,
it creates an expression that calls the ip
constructor.
Sourcepub fn new_decimal(src: impl AsRef<str>) -> Self
pub fn new_decimal(src: impl AsRef<str>) -> Self
Create an expression representing a fixed precision decimal number.
This function does not perform error checking on the source string,
it creates an expression that calls the decimal
constructor.
Sourcepub fn new_datetime(src: impl AsRef<str>) -> Self
pub fn new_datetime(src: impl AsRef<str>) -> Self
Create an expression representing a particular instant of time.
This function does not perform error checking on the source string,
it creates an expression that calls the datetime
constructor.
Sourcepub fn new_duration(src: impl AsRef<str>) -> Self
pub fn new_duration(src: impl AsRef<str>) -> Self
Create an expression representing a duration of time.
This function does not perform error checking on the source string,
it creates an expression that calls the datetime
constructor.
