Struct TvpEncoder 

pub struct TvpEncoder<'a> {
    pub schema: &'a str,
    pub type_name: &'a str,
    pub columns: &'a [TvpColumnDef],
}

TVP value encoder.

This provides the complete TVP encoding logic for RPC parameters.

Fields

schema: &'a str

Database schema (e.g., “dbo”). Empty for default.

type_name: &'a str

Type name as defined in the database.

columns: &'a [TvpColumnDef]

Column definitions.

Implementations

impl<'a> TvpEncoder<'a>

pub const fn new( schema: &'a str, type_name: &'a str, columns: &'a [TvpColumnDef], ) -> Self

Create a new TVP encoder.

pub fn encode_metadata(&self, buf: &mut BytesMut)

Encode the complete TVP type info and metadata.

This encodes:

• TVP type ID (0xF3)
• TVP_TYPENAME (DbName, OwningSchema, TypeName)
• TVP_COLMETADATA
• TVP_END_TOKEN (marks end of column metadata)

After calling this, use Self::encode_row for each row, then Self::encode_end to finish.

pub fn encode_row<F>(&self, buf: &mut BytesMut, encode_values: F)

where F: FnOnce(&mut BytesMut),

Encode a TVP row.

Arguments

• encode_values - A closure that encodes the column values into the buffer. Each value should be encoded according to its type (similar to RPC param encoding).

pub fn encode_end(&self, buf: &mut BytesMut)

Encode the TVP end marker.

This must be called after all rows have been encoded.

Trait Implementations

impl<'a> Debug for TvpEncoder<'a>

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

Formats the value using the given formatter.
