Describes a set of tests, that assert template variable tera:Value properties.

Variants

IsDefined

IsDefined: Assert that the variable is defined in the template.

IsNotEmptyString

IsNotEmptyString: In addtion to IsString, the condition asserts, that the string -or all substrings-) are not empty.

IsString

IsString: Assert, that if the variable is defined, its type -or all subtypes- are Value::String.

IsNumber

IsNumber: Assert, that if the variable is defined, its type -or all subtypes- are Value::Number.

IsBool

IsBool: Assert, that if the variable is defined, its type -or all subtypes- are Value::Bool.

IsNotCompound

IsNotCompound: Assert, that if the variable is defined, its type is not Value::Array or Value::Object.

HasOnlySortTagChars

HasOnlySortTagChars: Assert, that if the variable is defined, the values string representation contains solely characters of the filename.sort_tag_chars set.

IsTpnoteExtension

IsTpnoteExtension: Assert, that if the variable is defined, the values string representation is regeistered in one of the filename.extension_* configuraion file variables.

NoOperation

NoOperation (default): A test that is always satisfied. For internal use only.

Trait Implementations

impl Clone for AssertPrecondition

fn clone(&self) -> AssertPrecondition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssertPrecondition

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

Formats the value using the given formatter.

impl Default for AssertPrecondition

fn default() -> AssertPrecondition

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AssertPrecondition

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for AssertPrecondition

type Err = LibCfgError

The associated error which can be returned from parsing.

fn from_str(precondition: &str) -> Result<AssertPrecondition, Self::Err>

Parses a string s to return a value of this type.

impl Hash for AssertPrecondition

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AssertPrecondition

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

impl Serialize for AssertPrecondition

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for AssertPrecondition

impl Eq for AssertPrecondition

impl StructuralEq for AssertPrecondition

impl StructuralPartialEq for AssertPrecondition
