pub struct StructType(/* private fields */);Expand description
The Cloud Spanner Struct type which is composed of optionally named fields and their data type.
Implementations§
Source§impl StructType
impl StructType
Sourcepub fn new(fields: Vec<(&str, Type)>) -> Self
pub fn new(fields: Vec<(&str, Type)>) -> Self
Creates a new StructType with the provided fields.
Note that Cloud Spanner allows “unnamed” fields. If a provided field name is the empty string,
it will be converted to a None in the resulting StructType.
Sourcepub fn fields(&self) -> &Vec<(Option<String>, Type)>
pub fn fields(&self) -> &Vec<(Option<String>, Type)>
Returns a reference to this struct’s fields.
Sourcepub fn field_names(&self) -> impl Iterator<Item = &Option<String>>
pub fn field_names(&self) -> impl Iterator<Item = &Option<String>>
Returns an iterator over the names of this struct’s fields.
Sourcepub fn types(&self) -> impl Iterator<Item = &Type>
pub fn types(&self) -> impl Iterator<Item = &Type>
Returns an iterator over the types of this struct’s fields.
Sourcepub fn field_index(&self, field_name: &str) -> Option<usize>
pub fn field_index(&self, field_name: &str) -> Option<usize>
Returns the index of the provided field name.
Returns None if no field matches the provided name.
Note that this function ignores unnamed fields.
